Reduction of bug, see console for output

See the attached reduction.

A node transitions when hovered over. A parent (A) of that node has a webkitTransitionEnd event listener that calls event.stopPropgation(). A grandparent (B) has a webkitTransitionEnd event listener.

Expected result:
Since A's listener calls event.stopPropgation(), B's listener should not fire.

Actual result:
B's listener does fire (in attached reduction, see console for confirmation)

More info:
Problem observed on Canary 26.0.1393.0 
Does not repro on Chrome 24.0.1312.52 or Safari 6.0.2
