This is the first step towards descriptors. This will start cloning the component when it's mounted instead of mounting the first instance. This avoids an issue where a reference to the first instance can hang around in props. Since a mounted component gets mutated, the descriptor changes. We don't need to clone the props object itself. Mutating the shallow props object of a child that's passed into you is already flawed. Those cases need to use cloneWithProps. A props object is considered shallow frozen after it leaves the render it was created in.
