Title:
  Stray B being printed after switching workspaces with wayland

Status in GNOME Shell:
  Unknown
Status in gnome-shell package in Ubuntu:
  New

Bug description:
  The problem is that a stray "B" character is being printed to the
  terminal screen after switching work spaces with the Ctrl+Alt+{Up/Down
  arrows}.

  On the first workspace, I have a few applications running (Firefox is focused)
  On the second workspace I have gnome terminal 3.35.91 running in full screen 
(F11, so no window boarder) running.

  I Ctrl+Alt+Up Arrow to switch to the first workspace and do some
  things in FF and then Ctrl+Alt+Down Arrow to switch back to the second
  workspace and now see a "B" on the command line.

  This happens over and over.. I see the capital B on the commandline
  when I switch to this workspace where the terminal is fullscreened.

  Some things to note about when this happens:
  * This only happens with wayland
  * It happens fairly often but not 100% of the time
  * The key character created is always a "B"
  * I've only seen this key character be created on gnome-terminal
  * There are no journalctl logs generated when this occurs
  * I have to release the Ctrl+Alt+Up and then do Ctrl+Alt+Down to see the B. 
(If I keep Ctrl+Alt pressed and then do Up and Down, the B is not generated)
  * It seems more likely to happen if the first workspace is switched to, spend 
some time there just clicking things or typing or whatever, and then go back to 
the second workspace
  * It only happens if gnome-terminal is full screen'd with F11
