Reoccurring GitLab.com logouts

Summary

A customer of ours is facing frequently occurring logouts on GitLab.com. The timing varies, but it occurs multiple times a day for their entire team.

Steps to reproduce

Requested information from previous issue #121569 (closed):

• Browser name & version: Firefox 113.0.2
• Login mechanism (password login, Auth with Google, SAML etc) and any session settings in your IdP: Google SSO
• Is the time to log out consistent, like automatically logging out after x days or x hours?: "Log out is not consistent, other than multiple times a day"
• Is the logout while browsing or freshly starting a session?: "The log out does not only happen with fresh browser or session"
• Have you ticked the Remember me checkbox while logging in?: "Yes, the remember me box is checked"

What is the current bug behavior?

Users are forced to login multiple times a day.

What is the expected correct behavior?

Sessions last for the expected 7 day period on GitLab.com.
