The two happening at the same time can lead to the APZ autoscroll being
cancelled due to APZ receiving a main-thread scroll offset update.
To achieve this:
- The content process assumes APZ is handling the autoscroll until
told otherwise.
- If the parent process knows APZ won't handle an autoscroll, it
tells the content process via its response to the Autoscroll:Start
message. This covers all cases where APZ doesn't handle the
autoscroll, except the case where APZCTreeManager itself rejects
the autoscroll and it lives in the compositor process rather than
the parent process.
- If APZCTreeManager rejects an autoscroll and it lives in the
compositor process, it sends an 'autoscroll-rejected-by-apz' message
to the content process.

If we're trying to open a picker while one is already open, we should let the
first one close gracefully, that is, we should consume the popuphidden event,
otherwise the event will be fired when we re-add the listeners.

It doesn't work properly anyways due to a more general coordinate-system
problem on the Print Preview page (see bug 1393494).

Only send the msg "Browser:UnselectedTabHover" when someone requests for the
msg, it can reduce non-necessary communication.

This msg is used to notify the status whether the cursor is hovering over the
unselected tab or not.
It's used for the media's feature, resuming the background video decoding.

The intermittent failure is caused by the innate drawback of the present test,
it doesn't be consistent with the behavior how we actually block the media.
Since we always block media implicit, it would be set in nsGlobalWindow's ctor.
We would never call blockMedia directly, so we can remove the function.

When the block stauts of the window was changed, we would notify front-end side
to update the vaule, so that we can save it for session restore.

This patch creates a new print preview browser to host the simplified cloned-document
when Simplify Page option is used on preview. Also, this patch keeps track of what browser
should be presented, based on whether the 'Simplify page' checkbox is checked.

We could register media control related event after the tab has active media.
But we still need to register "audioFocusChange" in the beginning, because it
affect every tab even the tab has no active media.
