Bug, feature request, or proposal:

https://stackblitz.com/edit/angular-gkiyz4?file=app/tab-group-basic-example.html

The last tab is selected by default, with a small screen the tab is partially hidden by the arrow. I have to click on the right arrow to display the tab.

What is the expected behavior?

Display entirely the tab.
