custom event doesn't bubbled up in IE 7-9
It's quite hard to describe, see the demo:
original code here
When the inner div is clicked, the outer should catch the custom1 event. It's all ok in Chrome, but in IE, if the click event of IE is bind with jQuery, it's ok, when the click event is bind with the built-in attachEvent, things are broken.
I guess it's a bug. (I'm solving a problem with input event , I want to use the propertychange event to trigger the costumed input event, then found this bug.)
