How i tested: I tried on ubuntu with disconnected x11, with two users
(uid 1000, uid 1001). Starting with fresh ~/snap/thunderbird dirs. For
beta I also updated from a profile in use. LGTM

Title:
thunderbird snap does not work without x11 interface connected
Status in Mozilla Thunderbird:
New
Status in thunderbird package in Ubuntu:
Fix Released
Bug description:
When I disconnect the thunderbird from the x11 interface thunderbird
crashes saying it can not find the wayland socket. If I add a link to
the wayland socket inside the container thunderbird works fine. That
is on kubuntu 22.04 in a plasma/wayland session, MOZ_ENABLE_WAYLAND=1
is set on the host and in the container as well.
This also probably means that the thunderbird snap actually never uses
native wayland and falls back to xwayland (because the wayland socket
can not be found).
This unintended use of xwayland could be construed as a security
issue, but someone who mistrusts snaps using x11 (like me) will remove
the permission which leads to failure instead of a security issue.
$ snap run thunderbird ## BROKEN
