Good catch.

Yes, or else, the renderer has to make an exception and not shrink a
scripted prime.  MathPlayer does the latter, and the WebEQ Developer
Suite tools do the former.  Both of them also have logic to catch
mismarked up expressions like <mi>x</mi><mo>&prime;</mo> to insure
that that does display with the prime at the usual size and location.
It is a tremendous pain.
