Gijs Kruitbosch 4dd2872dab Bug 1707208 - ensure that file: dialogs display something in the focus permission checkbox label and add a test, r=jaws
Now that I finally wrote a test, I also noticed that we were trying to write the
checkbox permission value when the dialog gets aborted (ie removed because the
page disappears due to another page loading or the tab/window being closed),
which then threw an exception because the event target is the window rather than
the dialog element, and dialog.querySelector in maybeSetAllowTabSwitchPermission
fails.
