* There are a number of requirements on replacement events, which must be satisfied for the replacement
* to be considered valid:
* As with all event relationships, the original event and replacement event must have the same room_id
* (i.e. you cannot send an event in one room and then an edited version in a different room).
* The original event and replacement event must have the same sender (i.e. you cannot edit someone else’s messages).
* The replacement and original events must have the same type (i.e. you cannot change the original event’s type).
* The replacement and original events must not have a state_key property (i.e. you cannot edit state events at all).
* The original event must not, itself, have a rel_type of m.replace (i.e. you cannot edit an edit — though you can send multiple edits for a single original event).
* The original event must not, itself, have a rel_type of m.replace
* (i.e. you cannot edit an edit — though you can send multiple edits for a single original event).
* The replacement event (once decrypted, if appropriate) must have an m.new_content property.
*
* If the original event was encrypted, the replacement should be too.
