After reactivating disabled users there shared "public" folder isn't listed

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

I just found a strange behavior on the server V 27.0.2:

• first : all cloud users are in the same group ("cloud").
• for the group "cloud" there was a folder sharing on "public"
• I had temporarily disabled some users.
• After reactivation of these users, the group's "public" folder sharing was no longer displayed.
• I've deleted the sharing-option for "public" and recreated it for the group "cloud".
• After that, all users had the release in the folder overview again.

Steps to reproduce

see above

Expected behavior

after reactivating a user the folder sharing options for the group should work again.

No response

No files, tests, or entry points are named. Reproduce the group-share scenario by disabling and reactivating a user, then trace how user status changes affect group sharing and folder visibility; done means the existing group share remains listed after reactivation.
