[mdc-top-app-bar] Including core-styles does not work

Bug report

When I @use top-app-bar, it fails and can’t find the mixin core-styles.

Actual behavior

Webpack throws an error: ‘Undefined mixin’.

Expected behavior

Webpack should compile the source files.

It doesn’t mean anything, core-styles and the mdc-* import are the exact same thing, just a different way of including the CSS. One is a side-effect import and the other is more explicit.

The downside to the mdc-* import is that you need to remember to include another import if you want to use mixins. That (plus avoiding side-effects and preferring explicit style generation) is the reason we’re moving to the core-styles pattern.

@use '@material/top-app-bar/mdc-top-app-bar';
@use '@material/top-app-bar';

.mdc-top-app-bar {
  @include top-app-bar.ink-color(blue);
}

Is exactly the same as

@use '@material/top-app-bar';

@include top-app-bar.core-styles;

.mdc-top-app-bar {
  @include top-app-bar.ink-color(blue);
}

Ok so perhaps this will be done in the next few weeks? When you can’t @include top-app-bar.core-styles does this mean that all the sass mixins do not work or what does not being able to include core-styles effect?
