[Feature Request] Drop Permissions for yourself

Description

It should be possible to remove your own permissions for documents owned by other users, even if you don't have permission to edit the document.

Other

The permission system currently allows for the following situation:

1. User A grants view permission for some document to User B
2. User B looks at the document and then wants to remove their own view permission (for whatever reason, e.g., because they have already read it and no longer need it)
3. This is not possible, because User B does not have edit permission (only view permission).
4. Consequently, User B needs to ask User A to remove B from the view permissions.

This is especially annoying when the document has an inbox tag (which also can't be removed by User B due to the lack of edit permissions).

I'd argue that it should be possible for User B to remove himself from the permissions list without User A's help.
