A discussion issue has been reported by charleswalter where the body class from a category is not loading on topic pages upon initial load, but works after a hard refresh. charleswalter noted that this issue only occurs when accessing topics from a category, and not from the site’s homepage.
@codinghorror suspected this might be a bug and asked zogstrip to investigate. zogstrip pushed a fix, but later reverted it due to a class break on the topics list. A proper fix was then applied, which included a memory leak fix zogstrip.
Is this a bug? or is there a technical limitation for this?
When I first load a topic, we noticed that it does not render the body class from the forum it belongs to, until we do a hard refresh. Has anyone else noticed this?
body class=“docked archetype-regular”
After refresh…
body class=“category-entretenimiento-chismesgordos docked”
Example URL:

Interestingly, this problem appears when accessing topics from a category. When accessing topics from the homepage of the site (categories index, latest posts, etc.), the topic page appears to apply the body class accordingly.
I assume it has to do with the way the web application is rendering the topic pages.
The problem can be seen my visiting this category and clicking on to a topic.

Hmm this might be a bug, @zogstrip can you have a look first thing Europe morning?
Thanks for reporting that issue @charleswalter. I just pushed a fix 
https://github.com/discourse/discourse/commit/d15b698ac90cfca0a459bdda83e6731a4db8be48
FYI: I had to revert my previous fix as it broke the class on the topics list. Here’s the proper fix (with a memory leak fix 
)
