>+        [GTK][WPE] Remove Flatpak sandbox
>+        https://bugs.webkit.org/show_bug.cgi?id=199416
>+
>+        Reviewed by NOBODY (OOPS!).
>+
>+        The flatpak-spawn based sandbox was only a proof of concept and
>+        lacks flexibility for our needs so we ended up using it with very
>+        permissive permissions and it still imposed limitations that our main
>+        bubblewrap sandbox didn't have.
>+
>+        So in order to get as many applications using the sandbox as possible we
>+        will just remove this for now and focus on bubblewrap. At some point
>+        it may be possible to improve flatpak-spawn to fit our needs.
