SlotClone should not be passed a ref if it is a React.Fragment

[terrymun]

Bug report

Current Behavior

Consuming <Dialog.Portal> (and likely other components that uses <SlotClone> under the hood)) will cause the following error to be thrown when using Next.js 15:

Invalid prop ref supplied to React.Fragment

Expected behavior

Using <Dialog.Portal> should not be causing this error.

Reproducible example

TBD

Suggested solution

We should probably avoid passing ref to <SlotClone> component if it is a React Fragment:

primitives/packages/react/slot/src/Slot.tsx

Line 35 in 74b182b

<SlotClone {...slotProps} ref={forwardedRef}>

primitives/packages/react/slot/src/Slot.tsx

Line 35 in 74b182b

<SlotClone {...slotProps} ref={forwardedRef}>
