TypeScript: `DefaultProps` fields incorrectly required in `Props` type

[SheaJanke]

Description

In react-resizable@4.0.1, the bundled TypeScript types in build/propTypes.d.ts define Props as DefaultProps & { ... }, which makes all DefaultProps fields (axis, handleSize, lockAspectRatio, minConstraints, maxConstraints, resizeHandles, transformScale) required.

These props all have runtime defaults and should be optional. The previous @types/react-resizable (DefinitelyTyped) correctly modeled them as optional.

Reproduction

import { ResizableBox } from 'react-resizable';

// TS Error: Type '{ children: Element; width: number; height: number; }'
// is missing the following properties from type 'Readonly<ResizableBoxProps>':
// axis, handleSize, lockAspectRatio, minConstraints, and 3 more.
<ResizableBox width={800} height={350}>
  <div>content</div>
</ResizableBox>

This worked in previous versions when types came from @types/react-resizable. Since v4.0.1 ships its own types (via "types": "./build/index.d.ts" in package.json), TypeScript resolves the bundled types and @types/react-resizable is ignored.

Root cause

In build/propTypes.d.ts:

export type Props = DefaultProps & {
  children: React.ReactElement<any>;
  // ...
};

DefaultProps contains fields that all have runtime defaults, but the intersection makes them required at the type level.
