A bug that occurs when binding transitionend event to an element via jQuery's bind method.

[Wei Lou]

The event transitionend's argument object event can get two properties. They are propertyName and elapsedTime.

If we bind transitionend event via addEventListener, we can get these 2 properties properly. But if we bind transitionend event via jQuery's bind method, they don't exist. We will get undefined value when attempting to read them.

Thank you!

I've 2 suggestions.

jQuery may remove "originalEvent" property if possible. Because we actually don't use it when using "addEventListener".

If jQuery can't do it, you may mention "originalEvent" in jQuery's document of method bind ( http://api.jquery.com/bind).

It's documented here in the Event object page, which is linked from the on/bind pages:
