switchToFrame errors when given string

Expected behavior

If the iframe I am targeting has an id of "card-frame" and a name of "card-frame" and can be accessed through window.frames["card-frame"], should I be able to call switchToFrame("card-frame")?

Current behavior

Currently, an error is thrown:

InvalidArgument: [POST http://localhost:4444/wd/hub/session/a382b5f9b7e1d73deb28a1e03deb265e/frame / {"id":"card-frame"}] invalid argument: 'id' can not be string

Possible solution

😕

Steps to reproduce (for bugs)

Sample code:

<iframe id="card-frame" name="card-frame" frameborder="0" width="100%" scrolling="no" height="17" src="https://remote/iframe"></iframe>

it("should tokenize", async test =>
    test.remote
      .get("page.html")
      // Wait for inserted iframe
      .findByCssSelector("iframe#card-frame")
      .end()
      .switchToFrame("card-frame")

Environment

Intern version: 4.7.1 Node version: 13.5.0 NPM version: 6.13.4 Browser version: Chrome 79

Additional information

Using switchToFrame(0) works as expected.
