title: "Scrollable" mat dialog with component
body: <p>All I found about scrolling the dialog is about the overlay, but it is to describe the behavion off the dialog, but I need to scroll the content inside of it that is NOT in the mat-content, for it is an entire component.</p>
  
  <p>To open the dialog I am using:</p>
  
  <blockquote>
    <p>const dialogRef = this.dialog.open(CadastroPessoaComponent,
    dialogConfig)</p>
  </blockquote>
  
  <p>The dialog config is like this:</p>
  
  <blockquote>
    <p>dialogConfig.width = '90%';</p>
  </blockquote>
