Changing topic of one message via webapp doesn't update later messages

[neiljp]

If a sequence of messages are all in one topic, eg. topic A, message 1, 2, 3, then a topic header is shown for topic A and messages 1, 2, 3 are shown beneath it.

If we receive an event to update the topic of just message 2 (eg. to topic B) then it should show A for message 1, B for message 2, and A for message 3. Currently it seems we change the topic header of message 2, but message 3 doesn't have a changed topic header.

@amanagr This seems like it would be in the editing code you were working on?

@zulipbot claim.
I am not sure about how this should work, but I check for sure!
