title: MatDialog is not opening on Safari iOS 10
body: <p>I have a problem with opening dialogs on <strong>Safari iOS 10.3.3</strong> (Angular 5.2, Angular Material 5.2.4). I can open and close dialog multiple times but after several attempts dialog doesn't show up (dialog is visible in the <strong>DOM</strong> but is not shown to the user). When I trigger any style recalculation in dev tools dialog shows up. Switching browser tab and switching it back also helps.</p>
  
  <p>My problem is related to issue <a href="https://github.com/angular/material2/issues/10530" rel="nofollow noreferrer">https://github.com/angular/material2/issues/10530</a>.</p>
  
  <p>Do you have any workaround or idea how can fix it before Angular Material team will solve this? </p>
