           Summary: Parser bug: malformed p {color: red !important fail;}
                    declaration should be ignored
           Product: WebKit
           Version: 526+ (Nightly build)

        OS/Version: All
            Status: NEW
          Keywords: HasReduction
          Severity: Normal
          Priority: P2

p {color: red !important fail;} its incorrect according CSS 2.1 and should be
ignored by CSS parser. Unfortunately WebKit fails in this case.

It's interesting since CSSGrammar.cpp already has such code:

  case 182:
#line 1142 "WebCore/css/CSSGrammar.y"
    {
        /* When we encounter something like p {color: red !important fail;} we
should drop the declaration */
        (yyval.boolean) = false;
    ;}
    break;

but apparently something is broken.
