Automatic update from web-platform-tests Make ::backdrop inherit from originating element When ::backdrop was moved from the fullscreen spec to css-position-4, it was made tree-abiding, inheriting from its originating element. A few of the tests needed modification as they expected things like visibility and pointer-events not inherit from the originating element into the ::backdrop.
