Draggable render ref

[jmayergit]

The ref for Draggable's render function property is not actually passed, I checked the source code and the typescript signature also confirms this, yet the documentation suggests otherwise.

Draggable's render function should be passed a ref object like how Containers's render function is. I believe this is a bug.
