Which capabilities are you using?

What happened?

Mocks are no longer returning the bodies that are specified in the mock. Instead, they return in the format of:

{
  "type": "string",
  "value": "{'whateverYouSpecifiedAsThe': 'mock'}"
}

What is your expected behavior?

Mocks return the value specified, as is.

How to reproduce the bug.

Here's the code I'm using:

const mockResponse = {
  data: {
    someProperty: 123,
  }
};

const theMock = await browser.mock('https://some.site.com/someEndpoint', { method: 'POST' });

theMock.respond(mockResponse, {
  statusCode: 200,
  headers: {
    'access-control-allow-origin': '*',
    'access-control-allow-methods': '*',
    'access-control-allow-headers': '*',
    'content-type': 'application/json; charset=utf-8'
  },
  fetchResponse: false
});

In the network console in the browser, I will then see the endpoint returning this:

{
    "type": "string",
    "value": "{\"data\":{\"someProperty\": 123}}"
}

I believe this may have been introduced in #14360.
