The `TEST-UNEXPECTED-FAIL | checks that docIds are unique and increasing | in chrome | Expected 9 to be less than 0` unit test failed in a recent test run in https://github.com/mozilla/pdf.js/pull/13837#issuecomment-890511627, but also locally once for me. Perhaps this goes wrong because the test depends on state that might be mutated if the tests are shuffled?

/cc @Snuffleupagus since this unit test was added in https://github.com/mozilla/pdf.js/pull/13813/commits/b18620ac0f196c6fa5a9e54a53fa6b915e19e843
