ChangeLog: 1886c8abed/CHANGELOG.md (560-beta6-2021-05-31)
Even though this isn't explicitly noted in the Changelog, this seems to
have fixed the Element integration for me.
Additionally, I added a (hacky) `xdg-open` wrapper which removes the
`GDK_BACKEND` variable to fix the XWayland integration[1]. The problem
is that if a Firefox is running with Wayland (`ferdi` is running under
X11) and `GDK_BACKEND=x11` is passed to the `xdg-open` (and thus
`firefox`) process, Firefox refuses to start since another instance of
it is running under Wayland (but attempts to start in X11 mode because of
`GDK_BACKEND=x11`).
