研究方向
Investigate the CDK Overlay backdrop animation code in the Angular components repository, likely in packages/cdk/overlay/backdrop.ts or similar. Check if NoopAnimationsModule is properly propagated to the backdrop animation. Review the existing comment for any additional details. The fix may involve setting the animation state directly when noop animations are enabled.
