Description

As per Material 3 guidelines, container-color should use value surface-container-high token, but it's using value surface token.

We can override it by using dialog-overrides mixin like below:

@include mat.dialog-overrides((
  container-color: var(--mat-sys-surface-container-high),
));

But, it should be the default behaviour as per Material 3 specs.
