When using auctex to preview latex inline math formulas, the foreground

color of fraction line is not adjusted. I am using a dark theme, and for

normal math formulas, the foreground color will be correctly adjusted to

white; however, this does not work for fraction lines. E.g., in

$\frac{a}{b}$, the letters a and b will be in white (correct), but the

line between them will be still in black.

There are other objects that auctex fails to adjust colors from black to

white, e.g., the caption in a float environment, and the pseudocode in

algorithm2e environment, and the horizontal line part of a sqrt symbol

(in $\sqrt n$, the horizontal line above $n$ will be still black).

Thank you,

Renfei
