FileChooser: Need +rx mode to select folder
With directory=true I need
+rx rights on a folder for it to be included in the result.
Selecting the folder in the UI works fine. Also selecting multiple folders, all folders with +rx are included in the result, the others are not.
Interestingly with directory=false, it's possible to select files to which I have no access.
Selecting the folders works with gtk4 if the portal is not involved. I could not find any reason why that would be while looking into the code.
Use case: Selecting folders to exclude them from the backup, because they are not readable (World/pika-backup#138).
