Fade out HydrateFallback

[misha-erm]

Hello,
I'm curious whether it's possible to add exit animation for HydrateFallback.
In spa app I used to render some splash screen in the root index.html and later add .fade-out in useEffect. But in my Remix app splash screen is needed only for client-loaded routes

Since I don't control how HydrateFallback gets unmounted I'm not sure what's the best approach to achieve that.
I guess I can put useEffect inside HydrateFallback, clone splash screen before unmounting and fade out the clone. Or maybeview transition can be used... But sounds a bit over engineered

Thank you for any tips
