[Bug]: Trashbin filename collision - data loss

[gbt5]

⚠️ 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

If you have multiple files example.txt with the same name in different folders and delete them at the same time, only one is stored in the trashbin as example.txt.dTIMESTAMP_OF_DELETION, making it impossible to recover the other versions.

Steps to reproduce

1. create path_a/example.txt and path_b/example.txt
2. Delete both at the same time SOME_UNIX_TIME and have a bit of bad luck
3. only one example.txt.dSOME_UNIX_TIME in your trashbin

Expected behavior

see two different files, maybe with some hash of the path as part of the extension or at least ms timestamp resolution to reduce likelihood of collision
