Exponent Positioning Bug in Input Field

[wldeh]

Describe the bug:
When entering an exponent in a WAMAP answer box, the exponent initially appears in a lower position. If it is deleted (backspaced) and re-entered, it then appears in a higher position.

To Reproduce:
Steps to reproduce the behavior:

1. Go to a WAMAP math answer box/input field that
2. Type in an exponent (e.g., x^2)
3. Observe the position of the exponent
4. Backspace the exponent
5. Re-enter the exponent
6. Observe that the exponent is now displayed in a higher position

Expected behavior:
The exponent should consistently be displayed in the same position, regardless of whether it has been backspaced and re-entered.

While I've seen that positioning error happen, it doesn't happen consistently for me. I just tested in both Chrome and Edge, and didn't experience this behavior on the questions I tried it with. Does this happen in every question for you? Is there a particular question ID where you see this happen consistently?

I've been able to replicate the issue in certain cases. But for the life of me, I can't figure out what's causing it. Best I can tell, something in the mathquill exponent positioning code is getting tripped up by something in the page CSS, since the issue goes away if I change themes. But there is no obvious specific CSS causing it, nor anything in the positioning code that would explain why it would cause a problem. This unfortunately may be outside my ability to fix.
