[Webkit-unassigned] [Bug 37143] New: Chromium: worker exceptions are not shown in console

           Summary: Chromium: worker exceptions are not shown in console
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Minor
          Priority: P3
         Component: WebKit Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: caseq at chromium.org

workerExceptions.html:

<html>
<script>
var w = new Worker("workerException.js");
</script>
</html>

workerException.js:
throw { };

EXPECTED: Loading workerException.html should cause a console message "Uncaught
#<an Object>" to be printed to console.
ACTUAL: nothing happens

This stopped working after r56402, when semantics of
EventTarget.dispatchEvent() was slightly changed. The code in
WebWorkerClientImpl::postExceptionToWorkerObject(), however, was incorrect
before, as EventTarget.dispatchEvent() is supposed to return true iff no event
handlers called preventDefault() (i.e. event is unhandled).
