Random h1/h2 bolding after upgrading to 2.6.1

Noticed that randomly h1/h2 tags decided to be bold on:

  1. Some old topics
  2. Some old PMs
  3. Randomly in canned responses
  4. Randomly in new topics

I don’t see a pattern, it all seems random. Bug or setting? Why would canned responses be affected, and only some?

Can you share a screenshot? As far as I know H1/H2 tags are usually bold throughout Discourse… so is the problem that bold is inactive in some places?

Ignore my last post, I am dumb.
I will post screenshots shortly.
