Hey @paintedsky, thanks for your support, and glad to hear you're enjoying SN! The Advanced Markdown Editor is based on the open source SimpleMDE editor (https://github.com/sparksuite/simplemde-markdown-editor), and it definitely has its quirks, like what you see here. Some of the editors we develop ourselves (like the Simple Markdown Editor and Task Editor), but for this one, our best bet of getting this resolved is opening up an issue with the developers directly and seeing what they say. If they provide a fix, we can then pull this into our version of the editor.

Thanks for your speedy reply- it seems that SimpleMDE editor is no longer being maintained, so the possibility of having it fixed on their end seems unlikely.

Might be better to rework the extension based on a better editor? Obviously that's more work, but probably the best option in the long run. It looks like there's a fork of SimpleMDE called Inscryb that promises to be a drop-in replacement and might be worth looking at.

Ah interesting, didn't realize it was no longer maintained. Inscryb looks like it maintains it, but only stuff related to the wrapper, and not really deep code stuff. Yeah, will have to find another open source editor we can fork.
