Is JestDom.expect compatible/interchangeable with Jest.Expect.expect?

[jihchi]

bs-jest-dom: 4.0.0

For example, add following test case:

test("Jest.Expect.toEqual", () =>
  "Foo" |> expect |> Jest.Expect.toEqual("Foo")
);

to the file after line 480:

bs-jest-dom/src/__tests__/JestDom_test.re

Lines 474 to 480 in aa5fcb5

	test("not toBeChecked", () =>
	render({|<input type="checkbox" data-testid="input" />|})
	|> queryByTestId("input")
	|> expect
	|> not_
	|> toBeChecked
	);

save and run yarn test, you will get following error:

  We've found a bug for you!
  /Users/jihchi/Repos/bs-jest-dom/src/__tests__/JestDom_test.re 483:12-17

  481 │ 
  482 │ test("Expect.toEqual", () =>
  483 │   "Foo" |> expect |> Expect.toEqual("Foo")
  484 │ );

  This has type:
    JestDom.t => JestDom.expect
  But somewhere wanted:
    string => 'a

  The incompatible parts:
    JestDom.t (defined as
      Dom.eventTarget_like(Dom._node(Dom._element(Dom._baseClass))))
    vs
    string

Is that expected?

By the way, there is a work-around by changing expect to Expect.expect:

test("Expect.toEqual", () =>
  "Foo" |> Expect.expect |> Expect.toEqual("Foo")
);

I don't think they are compatible because I have typed it to only be called on DOM elements. I don't think there is a way for us to use each interchangeably. Open to any suggestions for improvements.
