--filter=recipient not working

[dorkmaneuver]

sudo -u www-data php .occ sharing:list --user myuser --filter recipient does not work as expected while sudo -u www-data php .occ sharing:list --user myuser --filter owner shows all the shares, where myuser is the the value of the owner-key. However, there are shares where there is the value "myuser" in the key "recipient", but the output is "[]". Version 1.2.0 on NC 27. This is not the expected behaviour, isn't it?
