Automatic update from web-platform-tests[css-contain] Disable layout containment for certain elements Text from the spec (https://drafts.csswg.org/css-contain/#containment-layout): "... if the element is an internal table element other than display: table-cell, or if the element is an internal ruby element, or if the element’s principal box is a non-atomic inline-level box, layout containment has no effect." The patch disables "contain: layout" for internal table elements but table cells, internal ruby elements and non-atomic inline-level boxes. Some of the new tests pass or fail incidentally due to crbug.com/785212, once that's fixed all the tests should be working as expected.
