Calender Dashboard Widget kills Browser Tab

[Nuube]

Steps to reproduce

1. Activate Calendar Tab
2. Call Dashboard

Expected behavior

Display Calendar Events

Actual behaviour

In spite of showing calendar entries the widget completely kills the browser tab. You can not navigate away from the dashboard, go backwards, even closing the tab does not work. You have to completely exit the browser.

Same behaviour has been observed with Vivaldi, Firefox on Linx Mint, Edge om W11 and Vivaldi on Android.

Firefox ask after a while if you want to "stop" the webpage.

The only exit form here is after login to fast enough enter the dashboard setting page and disable the calendar app, which I only managed to do by slowing down the browser by opening the debugger console.

Calendar app itself works fine.

Browser (console) logs would be nice

Hi @Nuube -

• Is this still occurring for you?
• Can you get the browser console output immediately prior to this event?
• Are you able to reproduce this behavior in a clean test account on your instance?

[joshtrichards]

If there are a lot of calendars or items, might be similar to #4758 & #4736

Closing due to lack of further follow-up info received.
