nested $Diff looses types in case of stateless functional react component

[villesau]

see this: broken example with stateless functional component

Flow should complain that passtrough property is missing but it doesn't.

However, if i change the component to class based, it works like it should:

working class based example

and if you take the other $Diff away, things start to work again:

example without double $Diff

This makes it impossible to write certain library definitions, like for react-redux.
