@radix-ui/react-dialog

Fixed a type regression where callback props that were previously declared as methods rejected handlers whose parameter is narrower than the prop's.

Allow explicit undefined for all optional types for compatibility with TypeScript's exactOptionalPropertyTypes flag.

Added support for multiple aria-describedby attributes.

Fixed nested, portalled layers being unusable inside a modal layer. A non-modal popover rendered inside a modal Dialog previously broke some user interactions because the modal layer's trapped FocusScope reclaimed focus, and its RemoveScroll only allowed scrolling within the modal content.
