Distinguish between manual close vs cancel of Dialog component

[tylerpashigian]

I have a Dialog with a form inside using TanStack Form. I have an apply button which essentially just closes the modal. However I would like to reset the form when either clicking the Dialog close button, backdrop, or the esc key. I know the Dialog has an onOpenChange prop, but there's no way to distinguish between a close and a "cancel" as far as I can tell. Any ideas?
