It's not, passing most of the times.
It's unstable. That doesn't mean thats bad.
And Firefox is passing Acid3. And always did.
I mean ACID1 and ACID2 failures are mostly regression that getting fixed a day after but still its not roughly stable.

Acid1 and Acid2 are reftests. The CI system ensures they continue to pass on every commit. Commits are not merged if they break the Acid tests.

No, it didn't always pass it. Acid3 didn't even exist when Firefox first came on the scene.
Firefox scores 99/100 for me.
Huh? Servo has passed Acid1 and Acid2 for, like, a year now. Servo doesn't pass Acid3, of course (although neither does Firefox anymore!).
I mean, I'm not going to claim that Servo is by any means Web compatible yet, primarily due to a long list of bugs and incompletely-implemented features. In terms of feature checklists, though, there's a lot done.
