Center the icon inside an Angular Material mat-icon-button

after-reset-center-ng-icon-btn.scss

// If you use some "CSS reset" (Tailwind, Bootstrap, 
// modern-normalize...), then mat-icon inside the
// Angular Material mat-icon-button will not be centered
// correctly - it will be shifted 2 pixels down.
// Here is the fix:
.mdc-icon-button {
  display: flex !important;
  flex-flow: row;
  align-items: center;
}
