#### What is the expected behavior? Setting `disableRipple` input of `mat-nav-list` or `mat-action-list` should prevent child `mat-list-item`'s from having a ripple effect when they are clicked. #### What is the current behavior? Setting `disableRipple` of `mat-nav-list` or `mat-action-list` does not cause the ripple on child `mat-list-item`'s to be disabled #### What are the steps to reproduce? [StackBlitz](https://stackblitz.com/edit/angular-zn7bu6?file=app%2Flist-overview-example.html) The StackBlitz demonstrates the ripple effect on the `mat-list-item` even after the `mat-action-list`'s `disableRipple` input is set to `true` #### Which versions of Angular, Material, OS, TypeScript, browsers are affected? "@angular/material": "7.2.1", "@angular/cdk": "7.2.1", "@angular/core": "7.2.0", #### Is there anything else we should know?
