Public bug reported:
Steps to Reproduce:
1. Start GNOME session.
2. Launch Firefox with a session restore containing N windows (e.g., 20 windows
from the previous session).
3. Attempt to switch workspaces using the keyboard shortcut (Ctrl+Alt+Right).
Expected Behaviour:
The workspace should switch from workspace 1 to workspace 2.
Observed Behaviour:
* The workspace switch animation to workspace 2 is executed but then the
animation is "rewinded" to return to workspace 1 with the focus changed to
another Firefox window.
* After using the "switch workspaces" shortcut N-1 times (e.g., 19 times),
GNOME successfully switches to the next workspace.
* In other words, each of the N-1 times that the "switch workspace" shortcut is
used, focus is shifted to one of the other open Firefox windows until they are
all cycled through, at which point the workspace is successfully switched over.
Why I am reporting this as a regression:
This problem did not exist up to and including in Ubuntu 25.04. Upgrading to
25.10 introduced the problem. And then I upgraded to 26.04 beta and found the
problem to still be present.
