2. Scroll down and click on a link that opens in a new tab.
3. Observe the behaviour.

[Expected results]:

• The page is opened in a new tab correctly.

[Actual results]:

• The UI is broken:
  • The theater controls appear and remain displayed over the url bar
  • The window size remains the same size as in theater mode.
  • The “New Tab Added” notification remains displayed.
  • After creating a new window the url bar doesn't curve and overlays the window in the corners.

• Attached a screen recording of the issue here.

I have verified this issue with the latest Firefox Reality version 11-141532306 (3c70b99) installed on the Oculus Go, HTC Vive Focus Plus, Pico Neo2 and Pico G2 4K headsets.
Now, the UI is not broken after opening a link to a new tab from theater mode.
