Automatic update from web-platform-tests Make 3D Rendering Context follow DOM tree for absolute/fixed position. When TransformInterop is enabled, make the notion of 3D Rendering Context and the should_flatten_inherited_transform state follow the DOM tree for absolute and fixed-positioned elements like it does for everything else. (This changes behavior only when RuntimeEnabledFeatures::TransformInteropEnabled().) This is one of a number of changes discussed in more detail in https://docs.google.com/document/d/1Up6NwhX0lWhASPCa0gADbV3kvEFGezbDxotAgKzfSUQ/edit Fixed: 1189985 Change-Id: If56d8092bdab4bd294c98d5b3c73ec4bc1d32009 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/2877917 Reviewed-by: Philip Rogers <pdr@chromium.org> Commit-Queue: David Baron <dbaron@chromium.org> Cr-Commit-Position: refs/heads/master@{#880630} -- wpt-commits: 8dee5dbb8c9b17ae876ad3b1f74043c0156487ba wpt-pr: 28877
