Resize handles only render on dynamic th's when ng-if is present

Not sure if something is wrong my setup, or this is a bug, but the only way I have been able to get the resize handles to render when using ng-repeat, is to include ng-if on the th's. Have tried variations using rz-col, but no luck.

Here is an example (remove the ng-if from th to see the issue): https://plnkr.co/edit/IerxPg4uUGtr46tUK9Uo?p=preview
