Description
Consider this JSFiddle:
A function is bound via $(window).load(). Then the load event is triggered on an external resource element (in this case an image):
$('img#foo').trigger(load);
- Actual output:
The load event bubbles up from the image to the window object.
- Expected output:
The event should not bubble. Native load events on images, iframes, ... don't bubble to the parent window, too.

Fix #10717, .trigger("load") on images can't bubble to window.
This means no manually triggered event named "load" can bubble, so avoid that name for delegated custom events.

This was introduced in 1.5 as a consequence of events now bubbling to window (as the W3C Events Level 3 spec says they should). However, you're right that the load event isn't supposed to bubble *at all*; a browser event doesn't but our triggered event does. That's easily fixable in 1.7.1 with the new special events hooks.
