We get previous input.value twice in HTMLInputElement::SetValue and nsTextEditorState::SetValue when setting input.value. Since nsTextEditorState::GetValue uses DocumentEncoder, it is expensive. So we should use old value as parameter of nsTextEditorState::SetValue if possible.

HTMLInputElement::IsValueEmpty uses DocumentEncoder when input element has focus. DocumentEncoder is slow, so we should use fast path (nsTextEditorState::HasNonEmptyValue) to check whether value is empty.

In order to facilitate the movement of code with side-effects called by Element::SetAttr to Element::BeforeSetAttr and Element::AfterSetAttr, Element::AfterSetAttr should have access to the old value of the attribute. This includes information about whether there was previously a value set or not.
Accomplishing this involved passing an additional argument through functions that find and change the old attribute value in order to ensure that we can differentiate between an empty old value and an absent old value (attribute was not set).
Note that while I tried to ensure that accurate values (and their absence) are reported to Element::AfterSetAttr, I largely ignored SVG. While the old value reported for SVG values should be however accurate the value already being reported to SetAttrAndNotify was, SVG elements do not currently report unset values properly because they will never pass a null pointer to SetAttrAndNotify.

This part is mainly to mark the channel as urgent-start if src related
attributes in HTMLImageElement and HTMLInputElement is set and the channel is
open due to user interaction. Unfortunately, we cannot just check the event
state just after creating channel since some loading image tasks will be queue
and execute in stable state. Thus, I store the event state in elements and
pass it to the place where create the channel.

The container of a radio group is the form, if it belongs to a form, or the
document object otherwise.
When moving a radio out of a form, we should add it back to a radio group.
Similary, before moving the radio to a form, we should remove it from the
original radio group.

Currently, attribute and child arrays (implemented in dom/base/nsAttrAndChildArray.h) start out empty. When cloning, the array ends up being resized multiple times in order to add the attributes and children that are being cloned from the original node. This would be quicker if the array was initialized to the correct size in the first place so that resizes are not necessary.
However, preallocating space for children is only necessary when performing a deep clone. Therefore, an additional parameter is being added to the Clone, CopyInnerTo, and CloneDocHelper methods to indicate whether preallocation of children should happen. Attributes are copied either way, so that part of the array is preallocated in both cases.

In order to reduce the size of HTMLInputElement for performance gain, we're
going to allocate input type=file related member variables only when type=file.
nsIFilePicker.displaySpecialDirectory is a string that can be set to TmpD,
Desk, or any other special directory value. The real value of this directory
will be read in the parent process.
Since the inner fields of date/time input are now <span> instead of <input>
text, we are adding an API for binding code to set the focus state of the
bound input element when inner fields are focused/blurred.

In the new architecture of Quantum DOM, all timer callback need a
specified event target. So, we add the new document arg to Start
function to get the event target from it. And update all callers.

In the new architecture of Quantum DOM, all runnables need a name label.
So, we add the new string-label arg to Start function, and update all
callers.

This will make the timing of the change more consistent between SetAttr and
UnsetAttr, and ensure that we have both the old and new type available in
AfterSetAttr.

This removes the requirement that BeforeSetAttr comes before AttributeWillChange
(which needs the preparsed new value).
