Inline question has weird form rendering

For an `InlineMultiQuestion`, consider this `question` as part of the problem file:

```
Now suppose we add an arbitrary extra node $t_{n+1}$
and form the new interpolant $p_{n+1}$.

If $\displaystyle\int_a^b \omega(x)\,dx = 0$, do we
always have
$\displaystyle \int_a^b p_n(x)\,dx = \int_a^b p_{n+1}(x)\,dx$?

If the original rule is exact for every polynomial
of degree at most $n$, what is the highest degree
polynomial it must then integrate exactly?

[[highest_degree]]
```

It renders as follows:

This is because somewhere between Crispy forms and Django's form handling, the output gets shoehorned into flexbox containers. This shouldn't be happening; the rendering should be analogous to normal markup. The form rendering is mainly driven by the `InlineMultiQuestionForm` constructor, based on the parsed question.
