Description
I get this error with the following steps:-
- Send a normal message event in a room with the sendEvent method
- Edit the event by changing its content and also add rel_type as m.replace and pass eventId of edited event
- Now try to do a reaction on the same edited event like this
- And also in vice versa case first we do a reaction and then try to edit the message in that case also we get the same error.
Then it gives this error **Error: [Immer] This object has been frozen and should not be mutated.**
If more information is needed I can provide it.

Research direction
Reproduce the failure through the sendEvent flow using an edited event and a reaction, testing both operation orders described in the report. Trace the event-edit and reaction entry points to identify where the frozen object is mutated. Done means both sequences complete without the Immer mutation error.
