Adding vertical-align: middle; on mat-icon-button fixes this issue.

But should we add this fix inside the libary?

Same for mat-mini-fab button - https://stackblitz.com/edit/tzatnc-nkmxrp?file=src%2Fapp%2Fbutton-overview-example.html

This is still an issue in latest release (18.0.4). The trick mentioned above does work nicely and should hopefully be adopted as a fix for the library.
