### Description

Hi there,
When using `mat-nav-list` with items that have an activated state, the primary color is applied on the activated item but the background color is missing.

### Reproduction

https://stackblitz.com/edit/angular-aovyvr

### Expected Behavior

Having same behavior than : https://material-components.github.io/material-components-web-catalog/#/component/list

(Scroll to "List with activated item" section and click on any list item)

### Actual Behavior

Only the font color is applied

### Environment

- Angular: 15.2.6
- CDK/Material: 15.2.6
- Browser(s): Chrome 112
- Operating System (e.g. Windows, macOS, Ubuntu): Any

Inizia dalla riproduzione collegata su StackBlitz e ispeziona lo stile dello stato attivato di mat-nav-list. Confrontalo con l’esempio collegato di elenco di Material Components, quindi verifica che un elemento attivato mostri sia il colore di sfondo previsto sia il colore del testo primario.
