Firefox is not suppressed if main window is not visible under X11.
- Open a OpenGL testcase (https://webglsamples.org/aquarium/aquarium.html)
- maximize it
- switch to different window
- CPU is still utilized and Firefox eats 150% CPU
It affects only Firefox under X11. Firefox/Wayland works as expected.
Other browsers (Chrome/Chromium under X11) can suppress rendering in that case.

Looks like we lost this ability in Bug 1723134 where X11/EGL was switched to swap interval 0 so we don't throttle rendering on X11 when window is hidden.

EGL swap interval has been 0 even before that bug and seems to be required for Xwayland (bug 1635186 comment 49), EGL/Nvidia and GLX/Nvidia (it's still 1 for GLX: wontfix = bug 1716049 = WR/Nvidia has been switched to EGL or SW WR), otherwise one hidden window blocks rendering in all others.
