Matrix -> xmpp message wasn't going through for one user, fixed by changing name

[asdofindia]

I'm not super clear about how to describe this issue.

There is an xmpp room which was bridged to matrix.

My display name on matrix was "Akshay S Dinesh (he/him)" initially, then I changed it to "Akshay S Dinesh (they/he)".

At this point, messages I sent to the room wouldn't show up on xmpp

At the same time user with name "Pirate Praveen (he/him)" was being able to send message to matrix room and have it show up at xmpp.

Then, I changed my name to "asd" and now my messages are going through too.
