Description of problem:

Bold text formatted with markdown in the journal is broken. This has always worked fine for me until today.

To see the problem, visit this page:
https://www.inaturalist.org/journal/trscavo/94606-salmon-hole

The text in red rectangles has been formatted as bold text.

At a glance, that page has no bold text, but in fact the page is heavily formatted. To see this, view the HTML source and note the STRONG tags in the body of the journal article.
