Angular 4动画不适用于Safari iOS 9.3

我的代码是：

的package.json

"dependencies": {
    "@angular/animations": "^4.3.2","@angular/cdk": "^2.0.0-beta.8","@angular/common": "^4.0.0","@angular/compiler": "^4.0.0","@angular/core": "^4.0.0","@angular/forms": "^4.0.0","@angular/http": "^4.0.0","@angular/material": "^2.0.0-beta.8","@angular/platform-browser": "^4.0.0","@angular/platform-browser-dynamic": "^4.0.0","@angular/router": "^4.0.0","@ngx-meta/core": "^0.4.0-rc.2","@ngx-translate/core": "^7.1.0","@ngx-translate/http-loader": "^1.0.1","angular2-moment": "^1.6.0","core-js": "^2.4.1","express": "^4.15.4","lodash": "^4.17.4","ng2-pdf-viewer": "^1.1.1","ng2-translate": "^5.0.0","rxjs": "^5.4.1","web-animations-js": "^2.3.1","zone.js": "^0.8.14"
},

landing.component.ts

import { Component,HostBinding,ChangeDetectionStrategy } from '@angular/core';
import { stateTransition } from '../routing.animations';

@Component({
  selector: 'cp-landing',templateUrl: './landing.component.html',styleUrls: ['./landing.component.css'],changeDetection: ChangeDetectionStrategy.OnPush,animations: [ stateTransition() ]
})
export class LandingComponent {
  @HostBinding('@stateTransition') '';
}

routing.animations.ts

import { trigger,state,animate,style,transition } from '@angular/animations';

export function stateTransition() {
  return trigger('stateTransition',[
    state('void',style({
      transform: 'translateY(50%)',opacity: 0
    })),state('*',style({
      transform: 'translateY(0%)',opacity: 1
    })),// enter animation
    transition('void => *',animate('.5s 500ms')),// exit animation
    transition('* => void',animate('.5s'))
  ]);
}

我试着想出一个小提琴,但我无法重现错误.
