ngx-bootstrap模态（ng6 / bs4）与angular2-draggable一起使用，不会拖动整个模态

Question

所以，我有一个在ng6和bs4.x中完成的应用

我从此处安装了angular2 / draggable：Angular Draggable

我在以下示例中使用了模式示例：ngx-bootstrap/modal

如果您向下滚动到：Component＃，您将看到下面的示例。

模板：

<button type="button" class="btn btn-primary" (click)="openModalWithComponent()">Create modal with component</button>

组件：

从'@ angular / core'导入{Component，OnInit};     从'ngx-bootstrap / modal'导入{BsModalService，BsModalRef};

@Component({
  selector: 'demo-modal-service-component',
  templateUrl: './service-component.html'
})
export class DemoModalServiceFromComponent {
  bsModalRef: BsModalRef;
  constructor(private modalService: BsModalService) {}

  openModalWithComponent() {
    const initialState = {
      list: [
        'Open a modal with component',
        'Pass your data',
        'Do something else',
        '...'
      ],
      title: 'Modal with component'
    };
    this.bsModalRef = this.modalService.show(ModalContentComponent, {initialState});
    this.bsModalRef.content.closeBtnName = 'Close';
  }
}

/* This is a component which we pass in modal*/

@Component({
  selector: 'modal-content',
  template: `
    <div class="modal-header">
      <h4 class="modal-title pull-left">{{title}}</h4>
      <button type="button" class="close pull-right" aria-label="Close" (click)="bsModalRef.hide()">
        <span aria-hidden="true">&times;</span>
      </button>
    </div>
    <div class="modal-body">
      <ul *ngIf="list.length">
        <li *ngFor="let item of list">{{item}}</li>
      </ul>
    </div>
    <div class="modal-footer">
      <button type="button" class="btn btn-default" (click)="bsModalRef.hide()">{{closeBtnName}}</button>
    </div>
  `
})

export class ModalContentComponent implements OnInit {
  title: string;
  closeBtnName: string;
  list: any[] = [];

  constructor(public bsModalRef: BsModalRef) {}

  ngOnInit() {
    this.list.push('PROFIT!!!');
  }
}

可拖动功能确实起作用，但是在我的示例中，会发生以下情况：

最后，这是我的@component（{...}）

我曾经用上面的代码替换ngx-bootstrap的代码中的基本模式...

请告知...
