[HTML-CSS] Scaled \sqrt overline position incorrect in Firefox

[dpvc]

In Forefox, the overline for \sqrt is misplaced in HTML-CSS output when the root is scaled. E.g., \Huge\sqrt{x^x}.

See the StackExchange posting for details.

It turns out that the one of the dimensions used in the position was not having the scaling applied to it, resulting in the bad positioning.
