Bug 1461945 [wpt PR 11026] - [css-contain] Layout containment abspos and fixed descendants, a=testonly
Automatic update from web-platform-tests[css-contain] Layout containment abspos and fixed descendants An element with "contain: layout" should be the containing block of any absolutely or fixed positioned descendants. The spec is very clear regarding this (https://drafts.csswg.org/css-contain/#containment-layout): "The element acts as a containing block for absolutely positioned and fixed positioned descendants." The patch just adds a new condition to ComputedStyle::CanContainFixedPositionObjects(). We already had the condition for paint containment before, so this takes advantage to add WPT tests to verify that case too. This patch causes that contain-layout-005.html starts to fail, but that's because of crbug.com/843329. There are more failing tests related to that bug, so TestExpectations is modified to reference it.
