mat-card elevation can no longer change with mat-elevation-z* classes

[functionportal]

Bug, feature request, or proposal:

I used to be possible to change the mat-card elevation using mat-elevation-z* classes, but now mat-card default elevation dominates any mat-elevation-z* classes

What is the expected behavior?

mat-elevation-z* classes should modify mat-card elevation

What is the current behavior?

mat-card elevation cannot be overridden by applying mat-elevation-z* classes

What are the steps to reproduce?

Apply mat-elevation-z6 class to mat-card. mat-card elevation is unchanged.
