描述

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.

What is the current behavior?

The tab is partially hidden by the arrow

What are the steps to reproduce?

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

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

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

    "@angular/animations": "^6.1.2",
    "@angular/cdk": "^6.4.3",
    "@angular/common": "^6.1.2",

    "@angular/core": "^6.1.4",
    "@angular/forms": "^6.1.4",

    "@angular/platform-browser-dynamic": "^6.1.4",
    "@angular/router": "^6.1.4",
    "material-design-icons": "^3.0.1",
  }

研究方向: Investigate the tab group component in Angular Material (likely in `src/lib/tabs/`). Focus on the scrollable tabs logic and CSS that hides tabs behind arrows. Check if the issue is due to a miscalculation of visible tab width or overflow handling. Review any existing tests for tab scroll behavior. The StackBlitz demo shows the last tab partially hidden by the right arrow on small screens; ensure tabs are fully visible before showing arrows.
