Deleted commits: 60fefea4 by Edgar Chen at 2023-07-31T17:56:34+00:00 Bug 1821884 - Ensure consistent state for fullscreen/pointerlock warnings; r=Gijs Fullscreen/PointerLock warnings are initialized with hidden="true", but change to hidden="" after being shown and hidden again. I think this started happening when we began using HTML elements instead of XUL as they handle hidden attribute differently.
