Session closed by protocol error

[Thomas]

Bug Description

When I open an existing session in Threema Web that had not yet experienced any errors like this I now get the following "popup" around 2 or 3 seconds after the session has restored itself:

Session Closed
The session was stopped due to a protocol error.

I cannot really find any specific thing I did, like send a big video file or anything.

Steps to Reproduce (for bugs)

1. load https://web.threema.ch/
2. click on Reconnect
3. wait a bit or click around between chats

Potential Solution

Forgetting the session "solved" this. Still reporting it since I only found very old bug reports like this from 2019 that indicated it should not happen after version 4.4.0, and well, here we are :)
So yes, I cannot exactly reproduce it, but the general problem might still exist somewhere in the code.

As such: please feel free to close if uninteresting since I cannot reproduce it and/or because you are working on a successor to the current web app.
