No, it's the use of /style/ (CSS) to determine /content/.

I guess it's okay as long as authors understand that their :before and :after content, and therefore generated text equivalents, might differ if the user rejects their styles/applies different ones.

But, if we replace content with an image with CSS, does that make the text disappear from the accessible name? Bit of a can of worms, really. :(
