--- Comment #4 from Joseph Pecoraro <joepeck at webkit.org> ---
This started failing with the new CSS Parser.

My guess is that this is not a valid selector:


This is the text from the CSS Selectors Module 3: Spec:

> Only one pseudo-element may appear per selector, and if present
> it must appear after the sequence of simple selectors that represents
> the subjects of the selector. Note: A future version of this
> specification may allow multiple pseudo-elements per selector.

I doubt it is very common, and given you worked around it, maybe we should close this as the new correct behavior.

What do others think?
