testcase

Here is a testcase. "blah" should align with the base of the msubsup.

See bug 95015 for a related change.

vertical aligns

WebKit rendering looks fine to me. The text is nicely aligned next to the <math> element. (see 2nd testcase)

Though FF renders it differently, but that's because they calculate the <math> element's height differently (they end up with a lot smaller box) which makes the vertical-align property almost non-relevant here.

so I believe 'vertical-align: baseline' should align with the base of the msubsup as opposed to 'bottom' (unless I miss something here)

I was considering vertical align for table cells which is interpreted differently than for inline elements:

I think my comment on bug 95015 was misleading. I found the align bug while trying to write reftests for bug 95015, but that's probably unrelated since vertical-align is not inherited.

Actually, perhaps the bug is not related to MathML at all. Bug 90335 is a similar issue with HTML-only elements. I'm guessing using a div as a workaround should work for the present bug too.

BTW, Gecko's height bug is: https://bugzilla.mozilla.org/show_bug.cgi?id=415413
