MassMessage fails to respect a user's partial block from the "User talk" namespace
English Wikipedia Beta Cluster:
05:54, 26 April 2019 DannyS712 talk contribs block blocked DannyS712 talk contribs from editing the namespace User talk with an expiration time of 2 weeks (log)
05:55, 26 April 2019 DannyS712 talk contribs block sent a message to User:DannyS712/mms (Test2) (log)
Since 21:18, 10 April 2019, the only page listed at User:DannyS712/mms was "User talk:DannyS712 test2" (permanent link)
06:01, 26 April 2019 MediaWiki message delivery delivers the message that I sent to User:DannyS712 test2 (diff)
Expected behaviour: MassMessages aren't sent to namespaces the user can't edit
Actual behaviour: MassMessage added to a user talk page, despite me not being able to edit that page myself
