DatePicker onOpen console error

Hi,

The first render of a DatePicker component with an onOpen prop throws an error: Unknown event handler property `onOpen`. It will be ignored.

Reproduction:

1. Open https://stackblitz.com/edit/react-xje2zdjc?file=app%2Fapp.tsx

2. The error will appear in the console

Expected behavior:

No errors in the console
