Maximum call stack size exceeded when disposing reaction in many onBecomeUnobservable

[upsuper]

Test the following code:

  function create() {
    const array = mobx.observable.array();
    let dispose: (() => void) | undefined;
    mobx.onBecomeObserved(array, () => {
      dispose = mobx.reaction(() => {}, () => {});
    });
    mobx.onBecomeUnobserved(array, () => {
      dispose?.();
    });
    return array;
  }

  const arrays = Array.from({ length: 10_000 }, () => create());
  const dispose = mobx.reaction(() => arrays.flat(), () => {});
  dispose();

Intended outcome:

It should not trigger any error.

Actual outcome:

It triggers "Maximum call stack size exceeded" error.
