Hello,

I just fixed this and submitted a pull request.

[https://github.com/discourse/discourse/pull/4760](https://github.com/discourse/discourse/pull/4760)

EDIT: To explain a little bit how I tracked the bug:

1. I tried reproducing and found out that it actually reproduces by changing a topic’s title.
2. I found out that there are two events that control the header and if the topic title is shown or not: `header:show-topic` and `header:hide-topic`.
3. Searched where `header:show-topic` is triggered and found a match when a topic is reloaded (which happens when a topic is edited).
4. I changed the code to trigger `header:show-topic` only if the the topic title is not visible (not the one from the header, but the proper one, `#topic-title`).
