* Convert useSES shim tests to use React DOM Idea is that eventually we'll run these tests against an actual build of React DOM 17 to test backwards compatibility. * Implement getServerSnapshot in userspace shim If the DOM is not present, we assume that we are running in a server environment and return the result of `getServerSnapshot`. This heuristic doesn't work in React Native, so we'll need to provide a separate native build (using the `.native` extension). I've left this for a follow-up. We can't call `getServerSnapshot` on the client, because in versions of React before 18, there's no built-in mechanism to detect whether we're hydrating. To avoid a server mismatch warning, users must account for this themselves and return the correct value inside `getSnapshot`. Note that none of this is relevant to the built-in API that is being added in 18. This only affects the userspace shim that is provided for backwards compatibility with versions 16 and 17.
