[lovegaoshi]

Current behaviour

Hi! I've noticed the portal element now may flicker when its exited via onDismiss, under the new arch. its fine when exited via onClose. its fine with the old arch.

Expected behaviour

portaled component does not flicker

How to reproduce?

Preview

N/A

What have you tried so far?

I have deduced its visibleRef.current is still true when at the end of onDismiss, so its shown again. so I removed it and it seems to work normally now

Not only it flickers on onDismiss, but even worse: any TextInput will flicker when changing text if it is within portal. I reproduced it here, shows both issues:

+ it does it on iOS too, so not only Android issue this
