Elmish subscriptions does not work with Feliz.UseElmish

[Zaid-Ajaj]

@alfonsogarciacaro :

@Zaid-Ajaj If I replace Feliz.UseElmish with Fable.React.UseElmish Elmish subscriptions work. Haven't checked what's the actual difference (maybe because Fable.React.UseElmish doesn't use the useSyncExternalStore polyfill?)
