Description Tim Nguyen (:ntim) 2022-11-28 21:34:42 PST

The initial version of ::backdrop used to support all elements, as it was appended as sibling renderer, rather than as a child one. 

It was changed to being a child renderer for hit-testing purposes in bug 233072.

The fullscreen API needs to support backdrop on all kinds of elements, so we should figure out a way to do so.
