This will be indented. Italics. Plain. Bold. Whatever.
While I knew what the problem was, it was a challenge to fix because of interaction between my own Weaver for bbPress and the bbPress support in WP Edit. There was some interaction so that my fixes were being overridden by WP Edit. Finally figured out how to disable WP Edit’s interaction, and now all should be well
I did let WP Edit know that it has the issue with Indent.
