Actual behavior
The library does not support such behaviour, as can be seen here, it uses getFurthestAway when there are multiple candidates.
Steps to reproduce
Droppable
of the same type wrapped by a parent Droppable
.
See Before
CodeSandbox in Demo

When there are multiple candidates, select candidate with highest zIndex. See #669

@oliver-goh, thank you for your suggestion. I'll do some investigation and see what I can do. I'm not making any promises, but hopefully, we'll be able to make improvements to the dropping mechanism when this scenario presents itself.
