What steps will reproduce the bug?

class Test {
  private abortController = new AbortController()

  public test(cb: (abortSignal: AbortSignal) => void, abortSignal: AbortSignal) {
    const signal = AbortSignal.any([abortSignal, this.abortController.signal])

    cb(signal)
  }
}

const registry = new FinalizationRegistry((heldValue) => {
  console.log(`${heldValue} has been collected`)
})

;(() => {
  const test = new Test()
  registry.register(test, 'test')

  const abortController = new AbortController()

  test.test((abortSignal) => {
    abortSignal.addEventListener('abort', () => {
      console.log(test)
    })
  }, abortController.signal)
})()

global.gc?.()

setTimeout(() => {
  console.log('the end')
}, 2000)

run with node --expose-gc test.ts

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

Every time

What is the expected behavior? Why is that the expected behavior?

the output should be

test has been collected
the end

because the test object is not referenced anymore

What do you see instead?

output:

the end

the test object is not garbage collected

Additional information

The issues seems to be caused by the cyclic dependency: test object => abortController field => abortSignal => AbortSignal.any result => cb function => test object

AbortSignal.any seems to prevent node from garbage collecting them all at once

使用 node --expose-gc 运行提供的复现，并检查 issue 中描述的 AbortSignal.any、AbortController 和 FinalizationRegistry 之间的交互。完成标准是测试对象被回收，并且输出同时包含“test has been collected”和“the end”。
