nzOkLoading is not working in NzModalService.confirm()

https://stackblitz.com/edit/ng-zorro-antd-ivy-2p6wxs?file=src/app/app.component.ts

Steps to reproduce

this.modal.confirm({
      nzTitle: 'Do you Want to delete these items?',
      nzContent:
        'When clicked the OK button, this dialog will be closed after 3 second',
      nzOkLoading: isLoading,
      nzOnOk: () =>
        new Promise((resolve, reject) => {
          isLoading = true;
          setTimeout(() => {
            isLoading = false;
            console.log('Stop button loading!');
          }, 3000);
        }).catch(() => {
          console.log('Oops errors!');
        }),
});

What is expected?

My expectation is as follows; After the modal is opened, the user clicks the OK button, the button loading is started, and then the API request is made. If an error is received from the API request, the button loading will complete, but the modal should not be closed. (The modal closes when I reject or resolve.) If the API request completes successfully, the button loading is complete and the modal is closed.

What is actually happening?

nzOkLoading is not working correctly. It doesn't detect the change in Promise.

Please try this

showConfirm(): void {
    let isLoading = false;
    this.confirmModal = this.modal.confirm({
      nzTitle: 'Do you Want to delete these items?',
      nzContent:
        'When clicked the OK button, this dialog will be closed after 3 second',
      nzOkLoading: isLoading,
      nzOnOk: () =>
        new Promise((resolve, reject) => {
          isLoading = true;
          setTimeout(() => {
            isLoading = false;
            this.confirmModal?.updateConfig({
              nzOkLoading: isLoading
            })
            console.log('Stop button loading!', isLoading);
          }, 3000);
        }).catch(() => {
          console.log('Oops errors!');
        }),
    });
  }
