What is the proper way to have a radical in a MathQuill answer blank send the `root( , )` construct to WeBWorK, instead of raising to a reciprocal power? I thought I knew how this worked, but my example is not working for a ~2.20 server, nor a 2.19 server, nor a 2.17 server. Here is my example below. Entering a radical expression with MathQuill, the answer is rejected because it has been converted to an exponent behind the scenes.

loadMacros(qw(PGstandard.pl PGML.pl contextLimitedRadical.pl));
Context("LimitedRadical");
$inverse = Formula("root(3, x)");
BEGIN_PGML
Enter a formula for the inverse function of [`f`], where [`f(x)=x^3`].
[`f^{-1}(x)={}`][_]{$inverse->cmp(mathQuillOpts => "rootsAreExponents: false")}
END_PGML
