Per spec, "border" is parsed as a non-negative integer, only mapped if nonzero
(though this is not observably different from mapping even if 0, except if user
or UA stylesheets style the border), and supported on img, object,
<input type="image">, but NOT embed, iframe, or marquee.
This matches the Chrome and Safari behavior, as far as I can tell. The
substantive change here is that we are removing mapping for the <embed border>
case.

Per spec, "hspace" and "vspace" are parsed as dimension attributes and are
supported on the following elements: embed, iframe, img, object,
<input type="image">, marquee. Except no one implements this for iframe.
https://github.com/whatwg/html/issues/4742 tracks the spec changing accordingly.
As far as hspace/vpace on <table> go, Safari supports them in both quirks and
standards mode, while Chrome doesn't support them in either mode. The HTML spec
doesn't have them supported at all, and neither does the quirks mode spec, so
I'm removing the quirks-only support we had to align with the specs and Chrome.

The spec allows non-integer values, but we don't have a good way to store them
in nsAttrValue yet. See https://bugzilla.mozilla.org/show_bug.cgi?id=1561440
HTMLTableCellElement::MapAttributesIntoRule can now call
MapImageSizeAttributesInto instead of manually mapping width and height, because
0 values (which it was excluding before) are now excluded at attribute parse
time.
For 'width' on HTMLTableElement I kept our old behavior for 0, which matches the spec
but not Safari or Chrome.
For 'height' on HTMLTableElement I kept our old behavior for 0, which matches
Safari and Chrome but not the spec. https://github.com/whatwg/html/issues/4715
tracks a possible spec change.
Same thing for 'height' on HTMLTableRowElement.
Same thing for 'width' on HTMLTableColElement.
The ParseImageAttribute call in HTMLMediaElement is not needed, because
HTMLAudioElement does not map any of those to style and HTMLVideoElement only
maps width/height, which it already parses.

`HTMLEditor` initializes selection ancestor limit when it receives `focus`
event. If `Document.execCommand()` is called immediately after an
ancestor of active editing host becomes new editing host,
`HTMLEditor::GetActiveEditingHost()` returns the new one, but selection
ancestor limit is still the previous one. This mismatch causes a lot of
bugs. Therefore, this patch makes `nsGenericHTMLElement` notifies `HTMLEditor`
of an element becoming `contenteditable`, and makes `HTMLEditor` update
selection ancestor limit only when the new editing host is ancestor of
old selection ancestor limit.

BindContext was going to have way more information at first, but then I realized
that most of the things I wanted to know were basically a flag away using the
parent node.
Still I think it's worth it, now experimenting with BindToTree will only mean
adding a field to a struct that's included from a couple cpp files, instead of a
massive pain.
I also think this is clearer, and doing this highlights quite a few
inconsistencies in our code which I've left untouched, but commented with
FIXMEs.
Steps are:
$ for file in $(rg 'nsresult BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's#nsresult BindToTree(Document\* aDocument, nsIContent\* aParent,#nsresult BindToTree(BindContext\&, nsINode\& aParent)#g' $file; done
$ for file in $(rg 'nsresult BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's# nsIContent\* aBindingParent) override#override#g' $file; done
$ for file in $(rg '::BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's#::BindToTree(Document\* aDocument, nsIContent\* aParent,#::BindToTree(BindContext\& aContext, nsINode\& aParent)#g' $file; done
$ for file in $(rg '::BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's#nsIContent\* aBindingParent)##g' $file; done
$ for file in $(rg '::BindToTree\(' | cut -d : -f 1 | sort | uniq); do sed -i 's#::BindToTree(aDocument, aParent, aBindingParent)#::BindToTree(aContext, aParent)#g' $file; done
$ ./mach clang-format
Then manual fixups.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
This patch moves all UA Widget calls to helper functions in Element.cpp. The helper function AttachAndSetUAShadowRoot sets the shadow root in a runnable, so that it is in the same order of NotifyUAWidget* runnables.

There's a few subtle behavior changes here, which I'll try to break down in the
commit message.
The biggest one is the EditableDescendantCount stuff going away. This
was added in bug 1181130, to prevent clicking on the non-editable div from
selecting the editable div inside. This is problematic for multiple reasons:
* First, I don't think non-editable regions of an editable element should
be user-select: all.
* Second, it just doesn't work in Shadow DOM (the editable descendant count is
not kept up-to-date when not in the uncomposed doc), so nested
contenteditables behave differently inside vs. outside a Shadow Tree.
* Third, I think it's user hostile to just entirely disable selection if you
have a contenteditable descendant as a child of a user-select: all thing.
WebKit behaves like this patch in the following test-case (though not Blink):
https://crisal.io/tmp/user-select-all-contenteditable-descendant.html
Edge doesn't seem to support user-select: all at all (no pun intended).
But we don't allow to select anything at all which looks wrong.
* Fourth, it's not tested at all (which explains how we broke it in Shadow DOM
and not even notice...).
In any case I've verified that this doesn't regress the editor from that bug. If
this regresses anything we can fix it as outlined in the first bullet point
above, which should also make us more compatible with other UAs in that
test-case.
The other change is `all` not overriding everything else. So, something like:
<div style="-webkit-user-select: all">All <div style="-webkit-user-select: none">None</div></div>
Totally ignores the -webkit-user-select: none declaration in Firefox before this
change. This doesn't match any other UA nor the spec, and this patch aligns us
with WebKit / Blink.
This in turn makes us not need -moz-text anymore, whose only purpose was to
avoid this.
This also fixes a variety of bugs uncovered by the previous changes, like the
SetIgnoreUserModify(false) call in editor being completely useless, since
presShell->SetCaretEnabled ended in nsCaret::SetVisible, which overrode it.
This in turn uncovered even more bugs, from bugs in the caret painting code,
like not checking -moz-user-modify on the right frame if you're the last frame
of a line, to even funnier bits where before this patch you show the caret but
can't write at all...
In any case, the new setup I came up with is that when you're editing (the
selection is focused on an editable node) moving the caret forces it to end up
in an editable node, thus jumping over non-editable ones.
This has the nice effect of not completely disabling selection of
-moz-user-select: all elements that have editable descendants (which was a very
ad-hoc hack for bug 1181130, and somewhat broken per the above), and also
not needing the -moz-user-select: all for non-editable bits in contenteditable.css
at all.
This also fixes issues with br-skipping like not being able to insert content in
the following test-case:
<div contenteditable="true"><span contenteditable="false">xyz </span><br>editable</div>
If you start moving to the left from the second line, for example.
I think this yields way better behavior in all the relevant test-cases from bug
1181130 / bug 1109968 / bug 1132768, shouldn't cause any regression, and the
complexity is significantly reduced in some places.
There's still some other broken bits that this patch doesn't fix, but I'll file
follow-ups for those.

Various places in dom/ use the pattern:
already_AddRefed<NodeInfo> ni = ...;
which is supposed to be disallowed by our static analysis code, but
isn't, for whatever reason. To fix our static analysis code, we need to
eliminate instances of the above pattern.
Unfortunately, eliminating this pattern requires restructuring how Nodes
are created. Most Node subclasses take `already_AddRefed<NodeInfo>&` in
their constructors, and a few accept `already_AddRefed<NodeInfo>&&`. We
need to enforce the latter pattern consistently, which requires changing
dozens of source files.
This matches other implementations and the spec for fallback content like:
<canvas><div>abc
(calling div.innerText).
We're treating the <div> as 'rendered' because it's not in a display: none
subtree, but that's not ok, since it is in fact not rendered.
This was added in bug 1226293, and Boris suggested this change, but roc opposed
because it'd be hard to spec properly in comment 15. Looks like the HTML spec
ended up merging roc's innerText spec, and now it's spec'd in terms of 'being
rendered'.
I think IsOrHasAncestorWithDisplayNone just doesn't work in any reasonable way
for stuff out of the flat tree. Thus I think this change is the right thing.
The canvas test fails because of bug 1485076.
