Extended matcher does not work properly (doc pasted example)

See original GitHub issue

Custom made matcher from documenation toBeWithinRange is working in scenarion like this expect(100).toBeWithinRange(90, 110);

But throws an error in scenario like that

expect({ apples: 6, bananas: 3 }).toEqual({ apples: expect.toBeWithinRange(1, 10), bananas: expect.not.toBeWithinRange(11, 20)});

Error:

expect.toBeWithinRange is not a function

I believe this is an issue with codesandbox’s version of Jest. This is because both when I copy the code from the docs into a new Jest project, and when I export the codesandbox project to zip, it works. Please report the issue to codesandbox instead.
