"done" should fail when called multiple times

I did some online searching and didn’t find any discussion, so let me know if this is as expected. Happy to do a PR if this should be correct behavior

🐛 Bug Report

Calling done() multiple times in one test should be a failure, but it succeeds

To Reproduce

it('should fail when done called second time', done => {
  done();
  done();
});

Expected behavior

Test fails with "done" called multiple times or some such message

Link to repl or repo (highly encouraged)

Above code snippet showcases issue. Looks like following test could be added to e2e failures:

test('done();done()', done => {
  done();
  done();
});

Run npx envinfo --preset jest

Hello, me and another student are trying to fix this issue for a course in college. However, it’s our first time working with jest so we are not so sure which files to run to reproduce this issue… Can you please replicate it in repl.it?

That would be great, thanks!
