Dialog content rerenders and StrictMode

[Isaacmaamouche]

Hello,

In StrictMode, I've notice that childrens of a Ariakit.Dialog are rendered not twice but four times.
I added a rerender counter and console.logged it, it doesn't go from 0 to 3, but from 0 to 1 twice : 0 1 0 1

I have reproduced the behaviour using Ariakit latest version in this codeSandBox
You can move the JustADiv component in and out the Ariakit.Dialog to witness the difference in terms or rerenders.

Is it an expected behaviour ?
Would this be considered a bug ?

Best regards 👋

Yes, that's expected. It's because the dialog is rendered in a portal. You can adjust it by setting <Dialog portal={false}> to see the difference.
