<pre>This started failing with the new CSS Parser.
My guess is that this is not a valid selector:
input::-webkit-slider-runnable-track::before
This is the text from the CSS Selectors Module 3: Spec:
<a href="https://www.w3.org/TR/selectors/#pseudo-elements">https://www.w3.org/TR/selectors/#pseudo-elements</a>
<span class="quote">> 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.</span >
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?</pre>
