P4A relatively minor issue that is not relevant to core functions

Description

Bug, feature request, or proposal:

I don't understand why the tabs are focused when touched and I don't think that it should.

What is the expected behavior?

To not keep focus on tabs like on desktop browsers:
desktop

What is the current behavior?

The focus is kept when tabs are touched:
mobile

What are the steps to reproduce?

Try yourself here : https://material.angular.io/components/tabs/overview

What is the use-case or motivation for changing an existing behavior?

Mobile UI should probably not have focus status since there is not keyboard navigation or should at least behave like in desktop browsers.

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

Angular 6.0.9
Angular Material 6.3.3
Android (Chrome), Windows (Chrome with touch screen simulation)
Typescript 2.7.2
Chrome
