Steps to reproduce:

Firefox Developer Edition 56.0b4 (64-bit)

* Set layout.css.servo.enabled to "true"
* Restart
* Created a rule whose selector is ".anchor * + *" (a less efficient version of :not(:first-child) if you will).
* Programmatically retrieve rule
* Look at selector

Actual results:

selector text is ".anchor **"


Expected results:

selector text should be ".anchor * + *"

The testcase in Bug 1391169 is nearly identical and the patch I'm working on there will resolve this, as well.
