bug: collection-repeat doubling up on margins

Working codepen w/ng-repeat: http://codepen.io/anon/pen/pvxoMZ
Nonworking codepen w/collection-repeat: http://codepen.io/anon/pen/bNmNba

Notice how w/collection-repeat the margin between the first card item and the search bar is twice as large. This seems to be an issue with collection-repeat. Hopefully my issue is clear, thank you!
