Description

I upgraded a site from 3.9 to 4.5.5 and now user permissions are incorrect. The User Groups all have the correct permissions and the User has the correct User Groups assigned, but the permissions do not match.

Steps to reproduce
  1. Start on Craft 3.9
  2. Add some User Groups with permission to Edit Entries for a Section
  3. Add that group to a User
  4. Upgrade to Craft 4.5.5
  5. Check the permissions for the user compared to the user group permissions
Expected behavior

User permissions match User Group permissions

Actual behavior

User permissions don't match any User Group

Research direction

No files, tests, or entry points are mentioned. Start by reproducing the Craft 3.9-to-4.5.5 upgrade with a user group that can edit section entries, then compare the migrated user's effective permissions with the group's permissions; done means they match after the upgrade.
