Hi Toke, I hope you had a nice vacation.

Thanks.  I think it's overdue, users have been complaining about not being
able to check before joining.  I'm rather pleased with the use of
a disclosure triangle, I think it works better than my initial prototype
that used a popup window.

Yeah.  This is due to

  https://bugzilla.mozilla.org/show_bug.cgi?id=1935371

The API that we use to get the list of devices is called enumerateDevices.
Of course, it's a great source of fingerprinting material, so it is
restricted in various ways by different browsers.  Chromium-based browsers
do not expose device labels before the user has granted the camera
permissions.  Firefox is more radical, it refrains from listing cameras and
microphones unless there is a camera stream already running.  Or something
like that, the exact behaviour is not documented.

In Galene proper, I work around the issue by populating the camera menu
a second time after the user has opened a camera stream (I try to
eliminate duplicates, but at least in Brave it doesn't work well, so you
end up with duplicate entries).  Here, it should be enough to reorder the
calls (open the camera stream first, then populate the menus).  Oh well,
another item for my todo list.
