Collapse to Function creates a return node that cannot be deleted

Collapse to Function creates a ReturnNode that cannot be deleted. When creating a new Function, the ReturnNode is not mandated like this, so this seems inconsistent.

Included is a screenshot of this causing a slight problem, with both the Set Speed node and the Completed exec on the ForEachLoop are both automatically connected to the ReturnNode.

Also occurs in Main: CL-2406189
