Bug 442433

SUMMARY
I am not quite sure it's a bug rather than a problem with my configuration, but for a couple of weeks (the problem didn't appear before) any chromium-based web browser run through Wayland with `--enable-features=UseOzonePlatform --ozone-platform=wayland` -- the usual way of forcing an electron application to render to the Wayland client -- completely freezes when setting a running video stream to fullscreen. The only escape hatch is Alt-F4 out of it.

STEPS TO REPRODUCE
1. From a tty, launch a Wayland session: `dbus-run-session startplasma-wayland`
2. Run microsoft-edge-beta (rpm source: 94.0.992.19-1) or brave-browser (rpm source: 1.29.80-1) with the flags `--enable-features=UseOzonePlatform --ozone-platform=wayland`
3. Point the browser to an embedded video, click the player widget to set it to fullscreen.

OBSERVED RESULT
The browser completely hangs. (Wasn't happening a couple of weeks ago)

EXPECTED RESULT
The browser runs the video fine.
