Is there a plan to support getters and setters?

Yes, will do that in a follow-up.

+        var event = document.createEvent("MouseEvents");

var event = new MouseEvent('click', {
  bubbles: true,
  cancelable: true,
  view: window
});

Hmm, if I use 'new MouseEvent', it crashes. This looks like a real bug and I'm
investigating.

Fixed. The reason of the crash was that I was caching the complied script per
Isolate, not per Context. The crash is gone by moving m_compiledPrivateScript
from V8PerIsolateData to V8PerContextData.
