"Search Function Issue: Inconsistent Results When Editing Messages in a Room"

[MATwave]

Description

If you edit a message and search for it using the old content, the message is found with the new content. However, if you try to search for a message with the new content, nothing is found at all.

Server - matrix.org.

I also asked questions in "Synapse Admins."

Steps to reproduce

1. I created an unencrypted room.
2. I wrote a message.
3. I found the message.
4. I edited the message.
5. Searched for the old content - found it.
6. Searched for the new content - couldn't find it.

I think this is essentially a duplicate of #8686.
