You are correct, that is a bad side-effect. I think the solution is to do

\ln\mathopen{}\mathclose{\left(\frac{x}{2}\right)}^2

so that the `CLOSE`

applies to the whole parenthetic group (instead of the `OPEN`

, as in my example). That will allow the position of the square to be correct, and will get the correct spacing before it.
