Steps to reproduce:

Hi,
mail and calendars (caldav) are provided by fastmail, the password for both is stored in the password manager.
This setup has worked nicely since forever.
After upgrading to 115.3, every time the calendars self refresh (I've set it to 1 minute) the external "Enter credentials" dialogs pops up.

Steps:

1. Remove all FM calendars
2. Click new calendar
3. Select "On the network"
4. Enter username and https://caldav.fastmail.com/ (the autodiscovery url)
5. Hit "Find Calendars"
6. Type password and save it in the password manager
7. All fastmail calendars show up and work properly
8. Close TB
9. Open TB again
10. Await the calendar refresh or manually sync
11. Get a weird web pop up - see screenshot 1 - with a spinner that keeps spinning forever. Note that the same url in firefox actually works - see screenshot 2

Actual results:

I get an external auth popup everytime the calendar syncs which never fully loads
This is a regression

Expected results:

No dialog shall popup

Small update since i've figured i can open the dev console.

First the issues seems to be related to cARDdav, the cAL part works fine it seems.

Second, in the console i got (slighly redacted):
Request to access cookie or storage on “https://app.fastmail.com/oauth/?client_id=XXXX&code_challenge=XXXX&code_challenge_method=S256&login_hint=XXXX%40XXXX&redirect_uri=http%3A%2F%2Flocalhost&response_type=code&scope=https%3A%2F%2Fwww.fastmail.com%2Fdev%2Fprotocol-carddav” was blocked because we are blocking all storage access requests.
