Description

Describe the bug
When I left DM with my own XMPP account on Matrix I can't write to it from XMPP.
When I open new DM from matrix side, messages from Matrix are comming to XMPP and XMPP messages are not being forwarded to Matrix.
Used public matrix.org bridge, not selfhosted one.

To Reproduce
Steps to reproduce the behavior:

  1. Create DM XMPP <-> Matrix (I wrote from XMPP to matrix, but should be same with matrix -> xmpp)
  2. Chat for a while to make sure it works.
  3. Quit DM from matrix side.
  4. Try to write from XMPP - nothing happens
  5. Create new DM from Matrix
  6. Now messages from Matrix to XMPP are appearing in same XMPP chat as before and XMPP messages aren't appearing anywhere in Matrix.

Used Conversations and Gajim on XMPP side and Element Desktop and Nheko on Matrix side.

Research direction

Start by reproducing the failure using the listed XMPP and Matrix clients against the public matrix.org bridge, focusing on the sequence where the Matrix-side DM is left and recreated. Done means messages sent from XMPP after that sequence are delivered to the recreated Matrix DM; the payload names no source files or tests, so the relevant bridge entry point must first be located.
