@eviltrout I want to fix this but not sure about what the right way is to route the event.

Repro:

- Edit first post
- Scroll down so title,category and tags are now in the header
- Edit category, tags or title
- Edit is not reflected in `header-topic-info` widget cause a reload of topic is not reflected

I can think of some hacks to fix this but not sure what the correct approach is:

- Option 1: have the header widget `observe` the category for relevant changes and rerender self. (downside, more observers and need to be careful about unobserving)

- Option 2: have the controller tell the widget to re-render when first post is edited unconditionally. (downside, no clear API for how to seek out the widget and rerender)
