Interesting, thanks for looking into it; I was wiped yesterday when I
ran into this.
What puzzles me is that even this simpler notebook will exhibit the
same problem. Just put this in one cell:
from IPython.core.display import HTML
save it and hit reload. Boom.
In this case there's no markdown, it's the html repr that gets loaded
on opening and has the same effect. I wonder if we can protect in
some way against this locking things up for users...
