The Angular team is now working with the MDC team to share more code to reduce duplication. To that
end, we are developing new, API-compatible versions of the Angular Material components backed by
MDC Web. [See @jelbourn's 2019 ng-conf talk](https://youtu.be/4EXQKP-Sihw?t=891) for more details.

## What we're working on now (Q4 2021):
* Continuing to create new, API-compatible versions of the Angular Material components backed by
[MDC Web][] ([see @jelbourn's ng-conf talk](https://youtu.be/4EXQKP-Sihw?t=891)). Much of our effort
is dedicated towards rolling out these new versions of the components across Angular apps
inside Google. This work will pay off with the following benefits:

  _getAfterAllClosed(): Observable<void> {
    return this._parentDialog ? this._parentDialog.afterAllClosed : this._afterAllClosedBase;
  }
  readonly _afterAllClosedBase = new Subject<void>();

  // TODO(jelbourn): tighten the type on the right-hand side of this expression.
  afterAllClosed: Observable<void> = defer(() =>
    this.openDialogs.length
      ? this._getAfterAllClosed()

    // order to force `max-width` and `max-height` to take effect.
    display: flex;
    max-width: 100%;
    max-height: 100%;
  }

  .cdk-overlay-backdrop {
    // TODO(jelbourn): reuse sidenav fullscreen mixin.
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;

    z-index: $overlay-backdrop-z-index;
    pointer-events: auto;

          ((options as any)[key] = (defaultComponentOptions as ComponentOptions)[
            key as keyof ComponentOptions
          ]),
      );

    if (options.path === undefined) {
      // TODO(jelbourn): figure out if the need for this `as any` is a bug due to two different
      // incompatible `ProjectDefinition` classes in @angular-devkit
      options.path = buildDefaultPath(project as any);
    }
