Something is wrong with logout + account switching

Is there an existing issue for this?

Describe the bug

I just logged out on SN as @ek after possibly having been logged in for a long time and I was also logged in as @oracle since a few days ago using account switching.

However, the logout didn't work (I was still logged in as @ek, at least according to the UI) and I saw some minified React errors in the console. However, I forgot to copy them before I refreshed the page. I have found no error related to this in the server logs searching all log streams of /aws/elasticbeanstalk/sn-env/var/log/web.stdout.log around the time period it happened.

When I refreshed the page, the logout worked. I was now only logged in as @oracle but logging out from that account didn't completely work. It switched to @anon but @anon still showed @oracle as an option to switch but clicking on it didn't work.

I then cleared my cookies and everything worked as expected from there again. I tried to reproduce to no avail.

I found this signout error in cloudwatch:

This happens when you logout and for some reason, req.cookies.multi_auth is undefined.
