[l2h] Math formula background color?

[Philipp K. Janert, Ph.D.]

Thanks for the advice. 
Using \htmlimage{noantialias} did the trick.

I tried all kinds of other stuff, too, such as
puttting spaces (\quads) in front and back,
and including a \vphantom{\Bigl|}, but neither
helped - as long as I kept the \bigl| , \bigr| in 
the formula. Taking them out made the 
problem go away. It's still a bit mysterious
to me.

Anyway, thanks for the advice, and I have
a path forward now.

Best,

		Ph.
