ng-repeat fired on hover

[gaui]

Is this normal behavior? Can this be avoided?

An expert says because the DOM element changes (ng-mouseenter triggering hover) for elements from the countries dropdown, the watchcollection is fired for the whole countries array so the ng-repeat above is always fired (thus the filter with the console.log). This can be fixed with track by country.code
