.live('click', handler) fires on disabled buttons with child elements in Chrome

[ms7821]

It's possible to receive events for a disabled <button> element as well as <input type="button">:

IE fires click for all of them, passing the button as the target and currentTarget. This was fixed in jQuery 1.5 in ​http://bugs.jquery.com/ticket/6911.

Chrome fires only for the <button> with a child element, passing that as the target. However, currentTarget is set to the button, so changing target.disabled to currentTarget.disabled should extend the fix to include Chrome.

Duplicate of #6911.

This bug still exists in 1.7.1, per the test case. It does look like changing to currentTarget will solve the problem.

Looks like it regressed in 1.7, probably due to #9393, which removed the specific liveHandler cases.

Fix #8165: Ignore events bubbling through disabled elements.

Although #6911 fixed the case where event.target was disabled, it missed the case where the target was a sub-element.
