Bug description

If you move the slides back, there is a moment when the slides zoom out and are positioned in a weird way.

Expected Behavior

To move back and next without loosing correct position.

Actual Behavior

I want to use the virtualization + loop + coverflow effect without getting that weird effect. I haven't seen in the docs any limitation between these properties so I expect that they should work together correctly.
