Summary: ^ TODO: the snapshot corresponds to the referring subtree update. However, the snapshot is getting applied as if it was the current top view of the running app. This is true in most cases but it doesn't for some. To solve this, we need to use the rootId for the subtree and apply the snapshot only if appropriate. Having said that, is good enough for the current submission as we keep iterating on it.
