Inequalities cause rendering issues when inside choices

See for instance, section 1 of [this page](https://editor.isaacphysics.org/#!/edit/master/content/questions/maths/algebra/manipulation/level2/inequalities_2_1.json) where `12 <p` explodes.

There's a workaround where you can just type an extra space after the `<` sign to avoid the issue.
