Recent releases of Marked have fixed Bear compatibility on Sonoma. As part of this, I’ve updated the Bear style for Marked, and written a little custom preprocessor to handle Bear’s (CommonMark) syntax properly. If you want a Marked preview styled to look exactly like Bear (with all of Marked’s options for export, navigation, and other features), you can use the Bear style in combination with the preprocessor, but if you just want Bear’s syntax properly interpreted, you can use the preprocessor with the style of your choosing.
