It looks like we're flushing style twice as often as Gecko, I haven't looked into why yet, but we have a flush from EQCSS.tryWithEval, and then the normal style flush because the stylesheets changed, I think. * Gecko profile: https://perfht.ml/2z7mSIe * Servo profile: https://perfht.ml/2z8i8lT

(If someone could confirm that measurements, it'd be nice too!)

Emilio is waiting for mstange's perf.html profile fix to show Stylo frames. Emilio says this bug is not a high priority because a web developer wouldn't design a real website like this.

This doesn't look worse than Gecko now I think. If some can confirm that'd be great.
