detach-root

[danjohansson]

When using defcard-om with an atom as state.
Navigating back and forth between the namespace list and the devcard keeps adding om roots that are not detached when navigating back.
I tried this as a workaround

    (will-unmount [_]
                  (println "unmounting this")
                  (let [pn (.-parentNode (om/get-node owner))]
                    (js/setTimeout (fn [] (om/detach-root pn)) 200)))

and it seems to do the trick.

Yeah I'm trying to fix this for all cases and this solution doesn't seem to work reliably, this is really hard to fix because we are rending a react tree within a react tree. It's limitation with om's current design.
