Ah, it means that WebKit doesn't implement BAD_STRING. See, for example,
this test case[2], where

  "; background: green; }

is tokenized into

  DELIM(;) IDENT(background)

in WebKit instead of

  BAD_STRING("; background: green; })

as required by both CSS 2.1 and the current css3-syntax.

It also means that, when encountering a case like url(a "), WebKit goes
into the string parsing path instead of treating " as a non-) character
like what css3-syntax requires.

Therefore, I disagree with the claim that the current BAD_URI token is
implemented by WebKit. Having said that, I think what css3-syntax says
is not be a bad idea performace-wise and I might favor it eventually.
It's just not matching any implementation as far as I can tell.
