Sadly, this is known.

Please don't ping the full team. @miaulalala is monitoring new tickets in this repo :pray:

@st3iny is https://github.com/nextcloud/calendar/issues/2960 back?

Feb 28 '24 18:02 ChristophWurst

Certainly looks a bit like it:

Brave version 1.60.125 Chromium

Would be interesting to see if the recently merged update of FC fixes this.

however, it doesn't allow me to reproduce the Maximum call stack exceeded bug on Firefox or Chromium.

Edit: testing the state before https://github.com/nextcloud/calendar/pull/5783 for comparison.

I can also not reproduce this with a build before https://github.com/nextcloud/calendar/pull/5783.
