Bug 109261 – Events wrongly propagated over shadow boundaries when we set a relatedTarget in FocusEvent constructor

• Status: RESOLVED
• Resolution: INVALID
• Component: DOM

[Kentaro Hara]

Currently we're creating a FocusEvent in Node.cpp in this way:

  RefPtr<FocusEvent> event = FocusEvent::create(eventNames().focusEvent, false, false, document()->defaultView(), 0, 0);
  EventDispatcher::dispatchEvent(this, FocusEventDispatchMediator::create(event.release(), oldFocusedNode));

Ideally we should create a FocusEvent in this way:

  RefPtr<FocusEvent> event = FocusEvent::create(eventNames().focusEvent, false, false, document()->defaultView(), 0, oldFocusedNode);
  EventDispatcher::dispatchEvent(this, FocusEventDispatchMediator::create(event.release()));

However, if we do so, fast/dom/shadow/shadow-boundary-events.html fails. It looks like that FocusEvent.relatedTarget has to be set not in the FocusEvent constructor but in EventContext::handleLocalEvents().

The same issue exists in BlurEvent, FocusInEvent and FocusOutEvent. We should fix them.

Marking INVALID since I cannot reproduce the issue.
