Hello,

This is on gnome-shell 3.38.6, fractional scaling 175%, running Firefox
91.5.0esr on Wayland.

Here is how to see the bug:

0. Make sure that restoring the previous session is turned on in the settings
1. Browse normally while multiple tabs are open
2. The browser freezes
3. Clicking on anything appears like nothing happens
4. Switching tabs and opening new tabs appear like nothing happens
5. Close the browser and reopen it again
6. All the clicks and new tabs are there

This is a regression from Firefox ESR 78 on Wayland. I'm not certain that this
is Wayland-specific.

Actual results:

The browser suddenly appears frozen, tabs cannot be switched, new tabs cannot
be opened, nothing happens when clicked on or typed.

However, all that activity still pass through because when I close and reopen
the browser (restore the previous session is turned on), I can see the result
of all the tab switching, clicks, typing and new tabs.

Expected results:

The browser does not freeze, nor apparently freeze.
