Screenshot showing upright greek symbols displayed as italic

The two sets of Greek symbols in Math, called Greek and iGreek, are supposed to
be upright and italic shapes, respectively.

However currently this distinction only works for uppercase symbols.  As an
example, %ALPHA and %iALPHA, wich gives upright and italic Α respectively; but
for lowercase symbols, both %alpha and %ialpha gives italic α.

This is also the case for the %var-xxx and %ivar-xxx symbols.

I have this problem with both 6.4.6 and 7.0.0 on Windows 10:
