[Bug]: Jest child process breaks Buffer instanceof Uint8Array

[noCharger]

Version

27.5.1

Steps to reproduce

1. Clone my repo and bootstrap

git clone https://github.com/opensearch-project/OpenSearch-Dashboards.git
yarn osd bootstrap

2. Create test file jest_debug.test.ts with simple test case

vi src/plugins/data_source/server/cryptography/jest_debug.test.ts

test('Debugging jest buffer behavior', () => {
    expect(Buffer.from("test")).toBeInstanceOf(Uint8Array);
});

3. Execute test file jest_debug.test.ts together with others

% yarn test:jest src/plugins/data_source/server/cryptography
yarn run v1.22.19
$ node scripts/jest src/plugins/data_source/server/cryptography
 FAIL  src/plugins/data_source/server/cryptography/jest_debug.test.ts
  ● Debugging jest buffer behavior

    expect(received).toBeInstanceOf(expected)

    Expected constructor: Uint8Array
    Received constructor: Buffer

      1 | test('Debugging jest buffer behavior', () => {
    > 2 |     expect(Buffer.from("test")).toBeInstanceOf(Uint8Array);
        |                                 ^
      3 | });
      4 |

      at Object.<anonymous> (src/plugins/data_source/server/cryptography/jest_debug.test.ts:2:33)```

4. Execute test file jest_debug.test.ts only

 % yarn test:jest src/plugins/data_source/server/cryptography/jest_debug.test.ts 
yarn run v1.22.19
$ node scripts/jest src/plugins/data_source/server/cryptography/jest_debug.test.ts
 PASS  src/plugins/data_source/server/cryptography/jest_debug.test.ts

Expected behavior

#4422 (comment) This solution should work both single test suite on single node process, but multiple test suites with child processes.

Actual behavior

The global config mentioned #4422 (comment) doesn't apply to child processes when there are multiple test suites. Very appreciated anyone helps me out.

Additional context

1. Closed Jest repo issue Jest breaks Buffer instanceof Uint8Array #4422
2. Created issue from OSD repo [Test] local unit tests failed  opensearch-project/OpenSearch-Dashboards#2459
3. Known issue from AWS Encryption SDK JavaScript instanceOf and different versions of the underlying Encryption SDK modules. aws/aws-encryption-sdk-javascript#126
4. Jest config from OSD repo in src/dev/jest/config.js

  globals: {
    Uint8Array: Uint8Array,
  },

There is one more repro with jest 29.2.2/node 18:

https://github.com/sergekh2/jest-buffer-test-fail/

It passes in node env, but fails in jsdom.

Judging by open/closed bugs, it seems like this issue is present in one form or another since jest 26.
