Plunkr Case (Bug Reports)
https://stackblitz.com/edit/primeng-tabmenu-demo-d47ewl?file=src/app/app.component.ts

Current behavior
When the p-tabMenu contains a model attribute that refers to an array containing items with a routerLink, all these items are being highlighted mistakenly.

Expected behavior
Only the menu item referred by the attribute activeItem should be highlited.
This used to work correctly on PrimeNG 13.0.0.

Minimal reproduction of the problem with instructions
e.g. of the items array that leads to an error:

  ngOnInit() {
    this.items = [
      { label: 'Home', icon: 'pi pi-fw pi-home', routerLink: ['a'] }, // Highlighted
      { label: 'Calendar', icon: 'pi pi-fw pi-calendar', routerLink: ['b'] }, // Highlighted
      { label: 'Edit', icon: 'pi pi-fw pi-pencil', routerLink: ['c'] }, // Highlighted
      { label: 'Documentation', icon: 'pi pi-fw pi-file' }, // Not highlighted
      { label: 'Settings', icon: 'pi pi-fw pi-cog' }, // Not highlighted
    ];
