So upon some further digging, it seems `gdk_display_get_name' always
returns "wayland-0" in that specific case.

I don't know what to do.  It looks like a bug in GTK, which I will try
to report in the coming weeks.  Would it suffice for browse-url to not
touch `WAYLAND_DISPLAY' until that is resolved?

Thanks.
