Relegate editing existing markdown to source mode

Use case or problem

in editing view, when the cursor is within previously-entered markdown, the markdown characters appear, shifting everything suddenly. if i’m only interested in editing content, not markdown, this can be disruptive. i’d prefer it if that didn’t happen.

Proposed solution

i suggest limiting the editing of previously-entered markdown characters to source mode. still allow users to enter markdown when source mode is off, but once the cursor leaves the markdown and the markdown characters disappear (as they currently do when source mode is off), they won’t reappear if the cursor re-enters them.
