I'm trying to define a character style based on a chemical formula I've
written in a document. It's in a specific font with a colored background. I
can create a style based on it, and everything looks ok, but when I apply it
to other formulas, the subscripts and superscripts are converted to normal
text.

In the style's details, under font settings, the superscript and subscript
checkboxes are checked and hashed out (in other words, they're not checked,
nor are they unchecked), which usually means that that particular option will
remain unaffected when the style is applied.

Is this a bug, or is there something I need to do to use character styles on
text with super/subscripts?
