The "mat-" prefix cannot be used in ng-material v1 compatibility mode

See original GitHub issue

I already updated @angular/material and @angular/cdk to v beta.12 but I got this error ERROR Error: The "mat-" prefix cannot be used in ng-material v1 compatibility mode. It was used on an "mat-list" element.
