                    generating contents
           Product: WebKit
           Version: 528+ (Nightly build)

               URL: http://jsbin.com/uvesad/14
        OS/Version: Mac OS X 10.6
            Status: UNCONFIRMED
          Severity: Normal

Screenshot of jsbin.com test case

Issue observed in Chrome 16.0.912.77 on Mac OS 10.6.8. Not reproducible in earlier WebKit builds (e.g. Safari 5.1.2).

Selectors like “[href$='foo/']:before” in conjunction with “content” declaration generate contents for all elements carrying @href, not just the ones actually matching the selector.

(FYI: was forced to set a “Version”. Not sure 528+ is accurate.)
