title: Indeterminate progress bar not working properly
body: <p>I am using MatProgressBarModule to add a linear indeterminate status bar at end of card-footer. Below is my code - </p>
  
  <pre><code>  &lt;mat-card-footer&gt;
      &lt;ng-content select="dashboard-card-footer"&gt;&lt;/ng-content&gt;
      &lt;section class="example-section"&gt;
      &lt;mat-progress-bar  [mode]="indeterminate"  value="20" bufferValue ="75"&gt; 
      &lt;/mat-progress-bar&gt;
      &lt;/section&gt;
    &lt;/mat-card-footer&gt; 
  </code></pre>
  
  <p>It shows on screen as determinate status bar. I have tried with different modes too i.e. query,buffer. But it only works as a determinate progress bar.</p>
