This does not seem correct.

1) This will break existing content. For example, "<a
href="foo"><textarea></textarea></a>": if the user presses enter in the textarea
to create a new line, they will now incorrectly navigate.

2) Does it make sense for contains(target) to ever be false?

My feeling is that you're in the right area but I am not sure of the correct
solution here.

Keyboard input events bubble, so I would expect that the textarea consumes the
Enter and doesn't send it to the parent <a> any more.

This default event handling is implemented in
EventDispatcher::dispatchEventPostProcess. I think that you have to check
whether the Node::willCallDefaultEventHandler(Event) implementations correctly
call Event::setDefaultHandled(true).

             event->setDefaultHandled();
             dispatchSimulatedClick(event);
             return;
         }

             handleClick(event);
             return;
         }
