expect toMatchObject shows "expected... to NOT match"

[dandv]

Describe the bug
If the assertion fails, expect(actual).toMatchObject(expected) shows that it expected actual "to NOT match" [sic]:

Steps to Reproduce

import { it } from '@std/testing/bdd';
import { expect } from '@std/expect';

const expected = {
  field1: 'abc',
  field2: 'def',
  foo: 'bar',
}

it('toMatchObject', () => {
  expect({ 
    field1: 'abc',
    field2: 'def',
    foo: 'baz',
  }).toMatchObject(expected);
});

$ deno test denobug.test.ts 
running 1 test from ./denobug.test.ts
toMatchObject ... FAILED (2ms)

 ERRORS 

toMatchObject => https://jsr.io/@std/testing/1.0.5/_test_suite.ts:218:10
error: AssertionError: Expected {
  field1: "abc",
  field2: "def",
  foo: "baz",
} to NOT match {
  field1: "abc",
  field2: "def",
  foo: "bar",
}

Expected behavior

The output should omit NOT .

Environment

• OS: Fedora Linux
• deno version: 2.1.2
• std version: not sure what to put here? @std/testing is at 1.0.5, expect at 1.0.8
