Log Message:
-----------
Account for perspective of the scroller when determining a transformed
child's contribution to layout overflow
https://bugs.webkit.org/show_bug.cgi?id=285282
rdar://142573993
Reviewed by Simon Fraser.
This patch aligns WebKit with Gecko / Firefox and Blink / Chromium.
Merge:
https://chromium.googlesource.com/chromium/src.git/+/602f4cdf9e0944a68fe91d12ead5b2ece186b8e3
This patch fixes the case, where WebKit was failing to account for perspective
of the scroller when determining a transformed child's contribution to layout
overflow and was not drawing any scrollbar at all.
