哪个@angular/*包是bug的来源？

service-worker

这是个回归吗？

不是

描述

这个问题跟#44044有关，后者已经关闭。
配置：

ServiceWorkerModule.register('ngsw-worker.js', {
            enabled: environment.minimized && environment.environment === 'staging',
            registrationStrategy: 'registerWhenStable:120000'
        })

更新检查在初始化时执行：

{
            provide: APP_INITIALIZER,
            useFactory: (service: ServiceWorkerService) => () => service.check$(),
            deps: [ServiceWorkerService],
            multi: true
}

ServiceWorkerService:

public check$(): Observable<unknown> {
        if (this.swUpdate.isEnabled) {
            return of(undefined).pipe(
                tap(() => this.info('Start check for update')),
                concatMap(() => this.swUpdate.checkForUpdate()),
                tap((value) => {
                    this.info('Update available', value);
                    if (value) {
                        this.growlService.showInfo('Application update is installed. Page will reload in 5 seconds.', 'Update');
                    }
                }),
                concatMap((value) => (value ? of(value).pipe(delay(5000)) : of(value))),
                tap((value) => {
                    if (value) {
                        this.beforeUnloadService.skip(() => {
                            reload();
                        });
                    }
                }),
                concatMap((value) => (value ? NEVER : of(undefined)))
            );
        } else {
            return of(false);
        }
    }

可以在我们的测试服务器上重现，如有需要，我可以私下提供链接。
