Wrong reported permissions on shared external storage

[PVince81]

Steps

1. Create an external storage "/local" of type Local applicable to the "admin" group only
2. Create a user "alice" in group "users"
3. Create an invisible tag "deny-this"
4. Apply the invisible to "/local"
5. Share "/local" with "alice" in the files app (using sharing tab)
6. Create a rule with the clauses "tag is 'deny-this'" and "user in group 'users'"
7. Login as "alice"
8. Try accessing "/local"

Expected result

"/local" appears greyed out and its "data-permissions" attribute must not have the readable flag
entering the folder shows a "forbidden" error

Actual result

"/local" is not greyed out and its data-permissions has the readable flag set (31)
entering the folder shows a "forbidden" error, so it's mostly a visual issue

Versions

Nextcloud 22.3.0
files_accesscontrol v1.12.1 and stable22

Sounds like a dup of #97 ?

The reason why folders are still listed, is because otherwise etags and other checksums for the sync clients would incorrectly defer cause problems all around.
