I’m seeing something odd in markdown documents in Devonthink 3.8.7.
Whether or not Mathjax support is enabled, the appearance of a dollar sign causes future wikilinks in a document to not be links in the preview mode.
In editing mode, the link will flip back and forth between being a link and being plain text in double square brackets.
For instance, [[the stock exchange]] anywhere after a dollar sign, whether or not the dollar sign is backslash escaped, may appear as plain text. If I put the cursor on the end of the line and hit enter, it will become a clickable link - except that when I use the back arrow to come back to this document, it’s once again [[plain text]].
Taking the dollar signs out and adding a carriage return restores the link to an actual link, and without the dollar sign somewhere in the preceding text it remains a link.
Mathjax is working fine.
