"Open out-of-scope URLs in default browser" doesn't close temporary tab when PWA is full screen on macOS

[jmadren]

Description

As stated elsewhere, when the "Open out-of-scope URLs in default browser" option is enabled, it causes a tab in the PWA to also open, which is subsequently closed. The problem is, at least on macOS (haven't tried Windows), if the PWA is in full screen mode, the tab that's opened in the PWA does not get closed automatically.

Steps to Reproduce

1. Make PSA full-screen (green button)
2. Click on a link that should open in the default browser
3. A blank tab is now still open in the PWA

Additional Information

Note that when in full-screen mode, the new tab in the PWA is actually a new window. I'm guessing that has something to do with this issue. But, if I choose New Default Browser from the menu in the PWA, it opens a new tab in my current browser with no tab or window opened in the PWA. Of course, New Window opens a new window for the PWA.
