beforeAll is fired even when not in the current describe.only context

[pixelastic]

🐛 Bug Report

When a test file has several describe() contexts, and one of them if focused using describe.only(), beforeAll() methods in all other contexts are still fired, even if no tests of those contexts are actually run.

This seems similar to #8379, but this time regarding .only() and not .skip().

To Reproduce

The following test file exhibits the issue:

describe('context', () => {
  describe.only('foo', () => {
    it('should work', () => {
      expect(true).toEqual(true);
    });
  });
  describe('bar', () => {
    beforeAll(() => {
      console.info("[beforeAll]: this should not appear");
    });
    beforeEach(() => {
      console.info("[beforeEach]: this should not appear");
    });
    it('should not be run', () => {
      expect(true).toEqual(true);
    });
  });
});

Output:

Expected behavior

None of the console.log should be called. The correct behavior of the beforeEach should also be applied to beforeAll.
