[blizzz]

Summary

• Shares from a group folder appear in the files list even if they are deleted
• the code checking whether a file is accessible was laid out only for the regular trash bin
• Needs one manual backport, because str_starts_with is not available in PHP 7.4

Checklist

• Code is properly formatted
• Sign-off message is added to all commits
• Tests (unit, integration, api and/or acceptance) are included
• Screenshots before/after for front-end changes
• Documentation (manuals or wiki) has been updated or is not required
• Backports requested where applicable (ex: critical bugfixes)

Needs one manual backport, because str_starts_with is not available in PHP 7.4

We have a polyfill for it from symfony if I remember correctly, so it should work as well on 7.4.
