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

What is the expected behavior?

the tests from above pass

What do you see instead?

the descriptors are inconsistent with other environments

Research direction

Start by running the provided Object.getOwnPropertyDescriptor assertions against the affected Node.js version, then trace how the global Headers, Request, Response, and FormData properties are defined. Done means the four descriptors match the expected writable, non-enumerable, and configurable values and the assertions pass.
