Shell keyboard navigation (after pressing Ctrl+Alt+Tab) doesn't work in Xorg sessions
Original bug filed at https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1965696:
As of [2022-03-18], I can no longer quickly get to system controls such as the Top Bar using the keyboard. According to the keyboard shortcuts settings window, I should be able to press "CTRL+Alt+Tab" to access these controls. When I press this key combination, I'm told by the Orca screen reader that I'm on the Top Bar. When I release the keys, focus jumps back to the window I was in before. I do not know if this is the case without Orca running. I'm unable to test without Orca running. I've reset Gnome settings, with no change.
