title: Angular Material "Platform" module fails to detect Edge browser
body: <p>I added the <a href="https://material.angular.io/cdk/platform" rel="nofollow noreferrer">Platform</a> module to my project, but it fails to detect Edge browsers (Material V12.2.7, Windows 10, Edge V94).</p>
  <p>I created <a href="https://stackblitz.com/edit/angular-ivy-afzrrv" rel="nofollow noreferrer">this StackBlitz</a> that tests the issue and prints the <code>Platform</code> output, and strangely enough, when I open the StackBlitz from an Edge browser, it fails to detect it.</p>
  <p>Does anyone else have this issue or am I doing something wrong?</p>
  <pre><code>import { Platform } from '@angular/cdk/platform';
  import { Component } from '@angular/core';
  
  @Component({
      ...
  })
  export class AppComponent {
  
      isEdge: boolean;
  
      constructor(private platformService: Platform) {
          this.isEdge = this.platformService.EDGE; // always false!
      }
  }
  </code></pre>
