           Summary: Worker exception handling does not match the spec
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebCore JavaScript
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: atwilson at google.com


Currently, worker exception handling doesn't match the spec (distilling section
4.7 of the Web Workers spec and section 5.5.6.5 of the HTML5 spec):

1) We need to expose errors via WorkerContext.onerror
2) If WorkerContext.onerror() does not return false (HTML5 5.5.6.5), then we
need to forward the error to the Worker object.
3) If the event is not cancelled by the error handler, then it is reported to
the user via the error console (or forwarded up to the parent Worker object, in
the case of nested workers).
