The widget for editing markdown has been replaced. It used to use a custom version of SimpleMDE called sealmde.

The format-on-paste functionality let you copy formatted text from e.g. Libreoffice Writer or Micro$oft Word and paste it. Then fragments that were originally in bold would be pasted wrapped in **, same for italics, bullet points, etc.

The code that handled this is in this commit:

This task is about recreating this functionality in the new Monaco based editor. Probably best to do this in the stimulus controller in sealgen: https://hub.sealcode.org/source/monaco-wrapper/browse/master/src/controllers/monaco.stimulus.ts$1
