[Bug]: Reported total size under personal files seems to include team folder size

Bug description

When going to 'personal files' I would expect the total personal size (as indicated in left bottom / quota usage) to match total size.

It doesn't do this. That would be arguably okay on 'all files' section, where it's somewhat clear it's counting the team folder sizes too - as they're also visible there - but the same total size is reported under 'personal files' which doesn't not list the team folder - yet comes to the same total which doesn't match quota usage.

Steps to reproduce

1. Get access to a team folder
2. Have files in personal and team folders
3. Notice total size under 'personal files' includes usage in team folders.

Expected behavior

Total size of 'personal files' should match quota usage.

Additional info

No response

No files, tests, or entry points are named. First reproduce the discrepancy with files in personal and team folders, then trace how the personal-files total and quota usage are calculated; done means the personal-files total matches the expected personal usage without incorrectly including team-folder usage.
