No, this is most likely an artifact of react-nested-router (https://github.com/rpflorence/react-nested-router) not currently preserving the scroll position. Definitely not a constraint imposed by React.

Edit: Or this may be due to the fact that we don't properly cache the fetched plugin list on the client side so we end up re-fetching it when you go back. Either way, this is not a React problem.
