title: How to add icon to mat-icon-button and have it same size as button without icon
body: <p>I want to ask how to add mat-icon to button tag but keep button height same as before.
  Button height is 40px and it should be 40px. But when I add mat-icon to button then button makes itself higher by few pixels. Is there any way to make it same height as right button and leave icon there? (40px) I would like to not change size of right button because it have height that I want. I want to make left button smaller.</p>
