[Bug]: Login always needed when you enter a NC url (e.g. Files / Talk) via browser bookmark

[Speed7811]

Bug description

In our company many people access NC via browser Bookmark, e.g. Files or Talk rooms. Now it happens every time that a login dialog occur from NC when a user click on the bookmark - regardless of whether you have already logged or not. This happens only if you access NC via browser bookmark. If you paste the url in the browser it doesn't happen.

Steps to reproduce

1. Login via URL on your nextcloud instance e.g. https://cloud.mycompany.com/
2. Save a URL as a bookmark of a room/call e.g. https://cloud.mycompany.com/index.php/call/znq3okmr or Files e.g. https://cloud.mycompany.com/index.php/apps/files/files
3. Close the browser completely (all tabs etc.)
4. Open the browser and the the url of your login instance e.g. https://cloud.mycompany.com/ => Now your are logged in => That's ok! This step is only to check that you are logged in.
5. Close the browser completely again (all tabs etc.)
6. Open the browser and click on the bookmark you saved in step 2. (yes it sounds crazy but it must be a bookmark - paste the URl will work) - repeat this step if necessary. Sometime it happens directly - sometime I need two or three tries.

Expected behavior

The NC url should be opened and the user is still logged in without any dialog. The user can use NC directly without doing any login.

Additional info

Info 1: We just updated last week from 28 one instance to 29 and another instance to 30 (Latest patch level). In <=28 it works many years without any problem.

Info 2: This doesn't happens if you are logged in, let the browser open and then click on the bookmark

Info 3: I can share a video if necessary.

Info 4: First I thought it was a Spreed thing but (See: nextcloud/spreed#14045) it looks like to be a server thing.
