How to insert checkbox into question text?

I'd like to insert a checkbox into the question text (not as a choice).

My question currently has this HTML:
`<input type="checkbox"/> Some text`

It looks like this in the Survey Editor:
!

But the actual survey doesn't show the checkbox:
!

When I inspect the code, it says:
`<input type="checkbox" class="QWatchTimer">Some text`

Is this an issue with underlying CSS? How do I override it?

Thank you!
