path with chrome URL's and XBL files. The assertion is triggered since the
binding is invalid.

In bug 1551961, a WM_NCMOUSELEAVE message handler was added to the Windows widget
backend so that we can detect when the mouse leaves a draggable region (since
draggable regions are hittest'ed as HTCAPTION, and are therefore "non-client").
Inside that message handler, we used the WindowAtMouse handler to determine whether
or not the WM_NCMOUSELEAVE was firing because the mouse was moving off of the
non-client area to client area, or moving out of the window entirely.
For reasons that are not particularly clear, on Windows Aero Glass, when clicking on
one of the min/max/close caption buttons, a WM_NCMOUSELEAVE message fires, and the
::WindowFromPoint call that WindowAtMouse uses causes another WM_NCMOUSELEAVE message
to be queued immediately after, so we end up in this situation where the message
loop is getting spammed by WM_NCMOUSELEAVE messages. Moving the mouse away from
the caption buttons seems to stop the spamming.
We have a function similar to WindowAtMouse called EventIsInsideWindow which
does not use ::WindowFromPoint, and this seems to sidestep the issue, while
being functionally equivalent.

We need to do this in order to not override the mouse cursor that we set in the
widget layer when hit-testing in the non-client region.
We were accidentally overriding before because the PresShell normally queues up a
synthetic mousemove event when the mouse is moving within the client region. That
mousemove cause the EventStateManager to update the cursor to match Gecko's
reckoning of the cursor CSS style of the underlying frame (which overrides the
cursor we may have set in the Windows non-client region hittest - for example,
one of the window resize cursors).
By clearing the mMouseInDraggableArea boolean when transitioning from a draggable
to non-draggable region in the non-client region, we make sure that we process the
WM_MOUSELEAVE message, which sends the eMouseExitFromWidget event into Gecko, which
effectively cancels handling of the synthetic mousemove.

Previously, `runRemoveContentTest()` was the last test which synthesizes
composition in the `<textarea>`. However, new test order move it to middle
of the other tests. Then, it hits an `MOZ_ASSERT()` in
`TextComposition::EditorWillHandleCompositionChangeEvent()` that detects a
bug. When editable element is removed from the DOM tree during a composition,
editor cannot listen to `eCompositionEnd` event. Therefore, when the editor
gets back, it still has destroyed `TextComposition` and keeps handling new
composition with the old one. Therefore this patch makes
`EditorBase::InstallEventListeners()` forget the destroyed composition.

To avoid populating the clipboard cache,
`nsContentUtils::IPCTransferableToTransferable` should set the
IsPrivateData flag on the output transferable BEFORE assigning data to
it, not therafter.
This patch includes a new regression test for this specific scenario.
The patch also includes fixes for incorrect IsPrivateData flags in some
other locations with `transferable->Init(nullptr)`, but without unit
tests.

When long tapping on input element, the behavior of virtual keyboard is different of Chrome. Firefox opens virtual keyboard, but Chrome doesn't.
So I would like to change to same behavior of Chrome.
Also, after this fix, action bar (copy, paste and etc) won't be disappeared immediately after it appears by long tap. Before applying this fix, virtual keyboard is shown, then focused element is scrolled to center. So action bar may be disappeared. But after applying this fix, focused element isn't scrolled. So action bar keeps same position.

Actually, long tap can set focus. But since it uses `nsIFocusManager::FLAG_BYMOUSE` flag, we cannot recognize whether setting focus is by long tap or not.
So I would like to add new flag `FLAG_BYLONGPRESS` and `CAUSE_LONGPRESS` that are by long tap.

The SpecialPowers set*Pref/get*Pref APIs currently use synchronous messaging
to set and get preference values from the parent process. Aside from directly
affecting callers of those APIs, it also affects callers of `pushPrefEnv`,
which is meant to be asynchronous, but is in practice usually synchronous due
to the synchronous messaging it uses.
This patch updates the getPref APIs to use the in-process preference service
(which most callers are expecting anyway), and also updates the callers of
the setPref and pushPrefEnv APIs to await the result if they're relying on it
taking effect immediately.
Unfortunately, there are some corner cases in tests that appear to only work
because of the quirks of the current sync messaging approach. The synchronous
setPref APIs, for instance, trigger preference changes in the parent
instantly, but don't update the values in the child until we've returned to
the event loop and had a chance to process the notifications from the parent.
The differnce in timing leads some tests to fail in strange ways, which this
patch works around by just adding timeouts.
There should be follow-ups for test owners to fix the flakiness.
