[Bug]: SIGNREQUEST incorrectly detected as an open handle #12775
Description
Version
28.0.3
Steps to reproduce
Run the following test via jest --detectOpenHandles:
const crypto = require('crypto');
test('should not detect open handles', () => {
const key =
'-----BEGIN PRIVATE KEY-----\r\nMC4CAQAwBQYDK2VwBCIEIHKj+sVa9WcD'
+ '/q2DJUJaf43Kptc8xYuUQA4bOFj9vC8T\r\n-----END PRIVATE KEY-----';
const data = Buffer.from('a');
const sig = crypto.sign(null, data, key);
});Expected behavior
crypto.sign is a synchronous operation. Once the test completes, I would expect Jest to not detect any open handles.
Actual behavior
An open handle is detected:
> jest "--detectOpenHandles"
PASS ./test.js
✓ should not detect open handles (2 ms)

Ran all test suites.
Jest has detected the following 1 open handle potentially keeping Jest from exiting:
● SIGNREQUEST
