Filters on ng-repeat "go crazy" with ng-mouse*

HTML Mouse events don't work as expected when bound to elements using ng-repeat with filters.

On a MacOSX 10.10 MacbookPro:
- Firefox: events fire apparently "at random" with many mouseenter and few mouseleave.
- Chrome: mouseleave event never fires and mouseenter fires on every mousemove.

Example: http://jsfiddle.net/pfk1v3z9/

Is there any way to avoid this?
I already tried to apply mouse events to an inner div hoping to not trigger the filter on every event with no luck.

ATM I work-arounded the problem grouping on the controller with a $watch on my original collection.
