What steps will reproduce the bug?

The property descriptors should match such that this test succeeds:

for (const global of [
  'Headers',
  'Request',
  'Response',
  'FormData'
]) {
  const desc = Object.getOwnPropertyDescriptor(globalThis, global)
  
  assert.notStrictEqual(desc, undefined)
  assert.deepStrictEqual(desc.value, globalThis[global])
  assert.ok(desc.writable)
  assert.ok(!desc.enumerable)
  assert.ok(desc.configurable)
}

How often does it reproduce? Is there a required condition?

No response

the tests from above pass

What do you see instead?
