Clicking on search result jumps to hidden edit event instead of edited message

### Description

This is quite annoying, and applies also for the labs pinning feature.

### Steps to reproduce
(the room I tried this in was encrypted)

- post message
- edit message
- search message
- search results include edits
- click on edit thinking it was the message
- timeline jumps to somewhere, but the post is nowhere to be seen (suspect: the edit is a hidden event here)

Describe how what happens differs from what you expected:
Instead, jump to where the original message is, but show the message (or diff if the current state doesn't include the search term anymore, or highlight a diff button, etc).
