Let me reopen this.

It sounds reasonabe, but there are some use cases that we must handle.

When I tried to add 'load' and 'error' events to the 'stop' list, some layout
tests in WebKit started to fail.
One of them is a fast/dom/shadow/shadowdom-for-image-dynamic.html.

We have some layout tests which depends on an assumption like the following:
  1. <img> element, which will be a shadow host, has a 'onload' listener.
  2. A user adds a shadow root to the <img> element.
  3. The listener registered on the shadow host should still receive a 'load'
event for the 'image'.

So we will break the compatibility in this case.
