// So subscribe to the frontendBackendModel once and flow in changes only if backendUnityModel is available.
// Note that we only flow changes, not the current value. Even though these properties are stateful,
// frontendBackendModel is not the source of truth - values need to flow from backendUnityModel. Also, due
// to model reload, we go through a few values before we stabilise. E.g.:
// * User clicks play, fb.Play is true, flows into bu.Play which switches to play mode and causes an
// AppDomain reload.
// * bu.Play becomes false due to AppDomain teardown, flows into fb.Play
// * BackendUnityModel is torn down and recreated (<- WARNING!)
// * bu.Play becomes true as Unity enters play mode, flows into fb.Play
// If we flowed the current value of fb.Play into backendUnityModel when it is recreated, we'd set it to
// false, triggering play mode to end.
// Step is simply since it's a non-stateful ISource<T>
