Created attachment 632228 [details] mouseenter event test User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:10.0.2) Gecko/20100101 Firefox/10.0.2 Build ID: 20120215223356 Steps to reproduce: In the attached test page, moved the mouse from the white area directly into the red <div>, which is nested inside a green <div> inside a blue <div>. Actual results: The mouseenter events were fired on the <div>s in this order: red, green, blue. Expected results: The mouseenter events should be fired on the <div>s in this order: blue, green, red. This is not specified in the spec (http://www.w3.org/TR/DOM-Level-3-Events/#event-type-mouseenter), but this is how Internet Explorer behaves and it makes much more sense.

Comment on attachment 635498 [details] [diff] [review] patch I think D3E should define the order.
I'll file a spec bug.
Andy, can you confirm this is fixed for you now with tomorrow's Nightly (2012-06-24)?
Where do I go to download the nighly?
Found it. Confirmed fixed. Thanks!
