Fix for issue #12854 where push and pull resets

The col-*-push-0 and col-*-pull-0 classes try to reset the positioning using 0% but this prevents the opposite direction positioning to freeze and not being set correctly.
To fix that, these must set the position to auto instead of 0% with means left:auto and right:auto instead of left:0% and right:0%.
