I tried the live demo here and accidentally typed in a couple of ´-characters at the start of a header. The editor froze and I couldn't delete it.

Just confirmed that. Opening the devtools performance shows (on my computer : i7) 1 keypress takes 40-80ms with a really deep tree of (value).

I think this is because our demo is generating and parsing HTML syntax(prism) in realtime. I didn't take time to optimize our demo.
