It's surprisingly the location of the DOM elements. See here, I've swapped the two elements, and now the result is _backwards_
http://jsperf.com/always-return-on-jquery-events/21
Can anyone with knowledge of the webkit internal DOM id-based key/hashtable shed light on this?
I'm guessing that for the 2nd child, when it's propagating upwards, it has to hit 1 more element -- that is, if it must reach the first child to get the parent. I'd hope that the structure is more optimized than a simple crawl to the first node to go upwards.
EDIT: Actually, I'm wrong. I edited the test to have 6 divs, and re-arranged the order of the tests. The tests still come in performance-wise from first-to-last, first performing the best. I really don't know what to think now.
