> Acid3, in particular, contains some controversial tests and no longer reflects the consensus of the Web standards it purports to test, especially when it comes to issues affecting mobile browsers.

Does this imply that the standards have changed on how some features are to be implemented? Or has the correct behavior simply never been specified precisely enough? Or does this simply mean that some of the features that Acid3 tests simply don't make much sense on mobile browsers?

Standards have changed. For example, CSS :first-child without a parent is now legal:

You can shift click the "A" in Acid3 to see what's failing.
