fix(scrolling): virtual scroll throw off if directive injects ViewContainerRef #16137

Merged

Fixes the virtual scrolling being thrown off and rendering the items in a wrong sequence, if there's a directive on the items that injects ViewContainerRef. The issue is due to the way we insert new views in a particular index. Rather than inserting the item at the index directly, we insert it and then move it into place. It looks like this behavior, coupled with Angular adding an extra comment node if something injects the ViewContainerRef causes the insertion order to be messed up.

Fixes #16130.
