In #19116 some logic was added so that we use insertBefore when an item is entering from the top, rather than appendChild. The problem is that an error will be thrown if the first item in the drop list isn't a sibling of the first draggable element.

Fixes #19359.

…ntermediate child

In angular#19116 some logic was added so that we use `insertBefore` when an item is entering from the top, rather than `appendChild`. The problem is that an error will be thrown if the first item in the drop list isn't a sibling of the first draggable element.

Fixes angular#19359.
