default behavior
should not force exit after root suite completion:
Uncaught UnexpectedError:
expected true to be false
at postmortem (test/integration/options/exit.spec.js:51:9)
at /home/runner/work/mocha/mocha/test/integration/helpers.js:69:7

2) --exit
when disabled

Additional Info
This is surprising given that we haven't changed any code since before these started. All commits on master are failing right now.
- Last commit with ✅: b41e985
- Two commits with no CI runs: 4b60c1a, 060f77d
- First commit with ❌: eca4fec
Edit: ah, I spoke too soon! 645469e is passing ✅. Updating this issue's title to indicate that the tests are nondeterministic. Hooray.
