Deal with empty content nodes

These should put some kind of error tag in.

I think this test reveals a regular MathJax bug with empty annotation tags.

The test is wrong.

annotation and annotation-xml are both optional inside semantics and you
can have as many as you want in either order, but there should be an
initial element (which is not annotation or annotation-xml) which is the
thing being annotated so the last two expressions in that test

and

/semantics>

are both in error but the test shows one as an error and one not, which I
don't think is justified.
(although rendering both as rather than an error is probably
reasonable

Thanks for the correction, @davidcarlisle. Either way, it's not really something ctop.js needs to concern itself with, wouldn't you say?

Yep. I've just made it so the code doesn't completely fail when a child node is missing.
