Describe the bug

Hello!

I'm getting a warning when using Mantine and React 19. I posted the message and stack trace below. It seems spiritually similar to #6446. Just thought I would give you a heads up - apologize if this warning is not helpful. It still works, as far as I can tell, so it is not urgent, at least for me. Thanks!

Accessing element.ref was removed in React 19. ref is now a regular prop. It will be removed from the JSX Element type in a future release.
