I'm going through old email and noticed I hadn't replied to this.  Sorry for
the delay.

There is no reason that radical should be special.  It is a bug in the test
image (and in MathPlayer).  On the other hand, it is hard to imagine a case
where the radical and some other enclose effect want to overlap -- usually
one would be nested inside the other (and hence, nested mencloses would be
used).
