Description
In a TeX expression such as $f_c'$, the prime is treated as a superscript. A prime can be rendered using character ′, U+2032. But the bottom of the ink in that glyph is higher than in characters used in other superscripts, such the "2" used in $x^2$.
If I place U+2032 into the second child of a <msup> element, Firefox lowers the glyph so that the prime is at the correct vertical alignment. At this date, Chrome Canary does no such adjustment.
Which behavior is correct? MathML-Core is silent on this question. I think the standard behavior should be spelled out.

Research direction
Start with the MathML-Core draft and the issue’s Firefox and Chrome Canary behavior comparison. Determine whether the standard should define vertical alignment for U+2032 in an msup element, and document the expected behavior and relevant wording when the specification is updated.
