If we have an animation of backdrop-filter, that needs to force the GraphicsLayer structure of a backdropLayer.

Comment 2 Dean Jackson 2015-05-22 14:49:59 PDT 
Without this, the element must have an existing backdrop filter or the animation does not work.

The test case I created indicates that this works fine in Safari 16.
