Regression from 2.x
Note: the same problem occurs on other places which should be fixed as well:
I can't reproduce this one on Mac Chrome / FF. Also not sure how we could fix it, only thing I can think of would be to register an unload event listener and then remove all notifications again but it depends which event happens first. showing the notification or unload
We can only reproduce this in Firefox so far, on both Linux and Windows. Tried to find a solution to this problem but really couldn't. Maybe someone else knows how to fix this issue?
I'm not even able to reproduce that with latest Firefox on Windows.
fyi Still occurs with Firefox 54 on linux.
Ah, I have been trying to figure out the root cause of this issue in our Cloudron installation for a while now. I can confirm that these error messages happen in Firefox 72.0.1 but not in Chrome. I am on linux.
Also occurs in Safari 13.0.5 (MacOS)
