Deck gl with Jest mock WebMercatorViewport object

[ariel-upstream]

Hi, I'm trying to mock the object of WebMercatorViewport with the fitBounds function.
but I can't get rid of the error:

(intermediate value).fitBounds is not a function
TypeError: (intermediate value).fitBounds is not a function

In my setupTests I'm using jest mock:

  jest.mock("@deck.gl/core", () => ({
  __esModule: true,
  WebMercatorViewport: jest.fn(() => ({
    fitBounds: jest.fn(),
  })),
  default: PropsViewer("DeckGL"),
}))

Sounds like you just need to bind your mock fitbounds method. Consult you jest documentation.
