VirtualList + ListGroup possible?

Questions
1

It seems VirtualList is highly dependent on the item height to work correctly, and I dont see any parameters that help with adding ListGroup heights to the equation, so does that mean the bottom line is you cannot have ListGroup + VirtualList?

In my attempts you always end up with that classic list scrolling fail.

After many attempts, my conclusion is that it is not possible to use both ListGroup and VirtualList as you might want to considering the contactlist parameter. If anyone else has a different answer, hopefully they’ll respond.
