This! This is a game-changer, thank you! Obsidian looks so clean, now.
I wanted to keep hashtag symbols, because my hashtags look like pills and it gets all cut off without the hash symbol. If anyone else wants this, just change this:
/* except list markers */ span.cm-formatting-list,
To this:
/* except list markers */ span.cm-formatting-list,
/* and hashtags */ span.cm-hashtag
