Categories are hidden in Discourse while the category definition topic is not modified. Indeed, I cannot see the `chat` category here.

While the [category definition topic for chat](https://meta.discourse.org/t/about-the-chat-category/37474) also was filtered out from the suggestions on the bottom of topic pages, it showed up as a new topic in the New-tab.
