Automatic update from web-platform-tests view-transition: Fix rendering of elements with clip-path on descendants The visual overflow rect computation code in ViewTransition assumes that if an element has a clip-path, its content will be sized to the bounds of that clip-path. The clip-path extent can be larger than the contents of that element. The above assumption is only true if the element with the clip-path is layerized. Otherwise the size of the overflow is an intersection of the element's painted content with the clip-path. This leads to incorrect overflow calculation for an element's overflow rect when its not layerized. Fix the above by forcing layerization on descendants of a named element if it has a clip-path. This is easier than knowing whether the content will be layerized by the paint step later.
