REGRESSION(268343@main): Crash under
WebCore::PositionedDescendantsMap::removeContainingBlock
https://bugs.webkit.org/show_bug.cgi?id=261998
Reviewed by Chris Dumez.
Some layout tests were crashing under
PositionedDescendantsMap::removeContainingBlock for WinCairo after
268343@main changed PositionedDescendantsMap::ContainerMap to
WeakHashMap. 'renderer' in removeContainingBlock wasn't a live
RenderBox object in the cases. Previously it has no problem because it
just used a raw pointer as a key.
Changed the key of ContainerMap to const RenderBox*.
