ModalProps variable names don't match

A npm run build errors out with

$ npm run build

> outage-form@1.0.0 build
> snowpack build

[@snowpack/plugin-typescript] src/__mocks__/Modal.tsx(6,3): error TS2339: Property 'DOMNode' does not exist on type 'ModalProps'.
[@snowpack/plugin-typescript] Error: Command failed with exit code 2: tsc --noEmit

This seems like a wrong variable name, maybe a renaming that was not fully implemented.
