Steps to reproduce:

1. Receive an email with an invitation. In my case, it was a MS Teams invitation.
2. The email header contains the header "this message contains an invitation to an event" with the buttons. Click the "More" button and then "Store copy". I have a localized TB, so the English wording may be different.
3. A "Select calendar" dialog will be displayed. I have several CalDav Google calendars (I don't use Provider for Google Calendar extension, just standard TB functionality). Only three calendars are writable, so the dialog displays three calendars for choosing to import in.
4. Press Cancel button.

Actual results:

The dialog is closed. But after a while, when the calendars are synchronized, the same dialog is displayed again. It's very confusing. You need to Cancel it again. But then it happens periodically, even if you synchronize the calendars manually. You need to restart TB to stop this.

Expected results:

The "Select calendar" dialog should be closed for good.
