Log Message:
-----------
[writing-mode] PositionedLayoutConstraints::computeBlockStaticDistance mostly
fails with nested content
https://bugs.webkit.org/show_bug.cgi?id=296570
Reviewed by Antti Koivisto.
This patch reimplements computeBlockStaticDistance to support statically
positioned out-of-flow
boxes across writing roots in nested context. See comments in
computeBlockStaticDistance for details.
* LayoutTests/TestExpectations: This test case was only passing accidentally.
