For me, #2 wasn't necessary, it worked only once I did #1.  I'm still
trying to figure out that one, though, as it's a pretty crippling
limitation, since it prevents you from doing any kind of subscript
with more than one character.

This is a known bug:  https://github.com/ipython/ipython/issues/1381.
Note that you can use \\\ instead for now.  We do need to fix it,
obviously, as something in our JS is going awry with handling math.

If I can find at least a workaround for #1 above I'll ping back.

Cheers,
