Correct test

My previous test was erroneous.

This one shows that vertical-align: middle; fails on a MathML element when rendered with Apple Symbol font.
The behaviour is correct with STIX fonts.

It is due to the fact that internally vertical-align: middle; calls xHeight() that returns 0 with Apple Symbol font as this font doesn't contain an x glyph (see https://bugs.webkit.org/show_bug.cgi?id=38377#c2).
