The sad news is that, as for WebKit and Blink, an event dispatching mechanism
has been *broken* in disconnected nodes for years.

See https://code.google.com/p/chromium/issues/detail?id=249582

I tried to fix that, but it caused multiple crashes. The previous attempt has
been reverted. That is still broken, I guess.

>From that, I believe no one is using event dispatch to make something useful in
disconnected nodes.
