Way for a wrapper to get notified of child layout changes

[mathieumg]

It seems there is no way for a wrapper component to get feedback when its children are changing the layout. I wanted to implement this demo by @vjeux but in the context of a wrapper: http://jsfiddle.net/Pm9ZZ/ Unless I'm doing something wrong (which is quite possible), this does not automatically scroll as in the initial example.

After talking with @spicyj on #reactjs he told me this was indeed something that would need to be addressed at one point.

@spicyj etc. Perhaps I'm misunderstanding the issue, but as far as React is concerned, this seems "by design" to me (not to say there aren't ways to work around it in user-land though).

Maybe. I know @vjeux and @jordwalke have done more thinking around this than I have.

There’s now APIs like Intersection Observer and React wrappers for it.
