Showing properly icon beside of text in mat-stroked-button

[bitbeter]

Bug, feature request, or proposal:

There is a bug in showing simultaneously icon and text in horizontal middle.

What is the expected behavior?

In mat-button icon and text showing correctly, but in mat-stroked-button this feature not working.

<a color="primary" mat-stroked-button>
   <span>تایید نهایی</span>
   <mat-icon>done</mat-icon>
</a>

<a color="primary" mat-button>
   <span>تایید نهایی</span>
   <mat-icon>done</mat-icon>
</a>

I Working in rtl direction mode so maybe this feature working well in normal ltr direction.

Thank You 😘
