Reactions not applied in fetched messages from history
When a message is fetched from the archive in Converse, it probably does not apply the previously fetched reactions
For example:
A message abc-def
sent at 1:00 has 1 associated reaction stanza uvw-xyz
sent at 8:00
If the message is fetched in another batch (loop), the reaction (being more recent in time) could not be applied to it in the UI
