When the **full category description** is showing, I also encounter this on Theme Creator and on my dev instance. I’m looking into it. I suspect it’s because the route changes but the tracked variable does not.

UPDATE: I have added an expand/collapse functionality for category descriptions here. @nathank Also fixed the bug in:  
[https://github.com/naidihr/discourse-category-headers/pull/22](https://github.com/naidihr/discourse-category-headers/pull/22)

With a little nudge from Ask Discourse for using `willDestroy` with the router service.
