@erikjohnston and I just spotted a new source of stuck notifications and other excitement with reactions... 😖

In a encrypted room, reactions are currently encrypted just like other events and end up with the message type m.room.encrypted. The default push rules for encrypted DM rooms notify for any message of type m.room.encrypted, so this will include reactions in such rooms.

Riot should now be advancing your read receipt past reactions (thus clearing the stuck notification), but @erikjohnston has observed this not working at least in one test case. (Further investigation is needed work out what the bug is here.)

On related note, it is a bit silly that apply the typical encryption path to reactions (including content ciphertext and setting the type to m.room.encrypted) because the relation data is sent around in the clear anyway. (We have separate future plans to specially encrypt just the reaction key.) It also prevents the server from aggregation reactions altogether, as it currently is watching for events with type m.reaction, but that won't be true in an encrypted room.

I added a comment to the MSC to suggest changing the event type for reactions.

Disable event encryption for reactions
59c4e2c 
For reactions, there is a very little gained by encrypting the entire event, as
relation data is already kept in the clear. Event encryption for a reaction
effectively only obscures the event type, but the purpose is still obvious from
the relation data, so nothing is really gained. It also causes quite a few
problems, such as:

  * triggers notifications via default push rules
  * prevents server-side bundling for reactions

The reaction key / content / emoji value does warrant encrypting, but this will
be handled separately by encrypting just this value.

See matrix-org/matrix-spec-proposals#1849 (review)
Fixes element-hq/element-web#10130

I have edited this capture that only the "notification" part has been fixed. The "stuck" part is not yet fixed since we don't understand the cause yet. We should use a separate issue to track that.
