angular 2 router hybrid app: url reverts back after navigate

Question

Every route change is rendering the correct component but has issue with path.
For example navigating from /items to /add-item changes and url for a second but then reverts it.
It happens on every page no matter from where to start and where to go.

Navigation

<a routerLink="/add-item">Add item</a>

Main app.routes.ts

export const appRoutes: Routes = [{
    path: 'brokers',
    pathMatch: 'full',
    redirectTo: '/'
},
{
    path: 'sellers',
    pathMatch: 'full',
    redirectTo: '/'
},
{
    path: 'buyers',
    pathMatch: 'full',
    redirectTo: '/'
},
{
    data: { name: 'pageNotFound' },
    path: '**',
    redirectTo: '/404'
}];

home.routes.ts

export const homeRoutes: Routes = [{
    component: HomePageComponent,
    data: { name: 'homePage' },
    path: ''
}

page-not-found.routes.ts

export const pageNotFoundRoutes: Routes = [{
    component: PageNotFoundComponent,
    data: { name: 'pageNotFound' },
    path: '404'
}]

add-item.routes.ts

export const addItemRoutes: Routes = [{
    component: AddItemComponent,
    data: { name: 'addItem' },
    path: 'add-item'
}]

items.routes.ts

export const itemsRoutes: Routes = [{
    component: ItemsComponent,
    data: { name: 'items' },
    path: 'items'
}];

All modules' routes are declared in import section like this

RouterModule.forChild(addItemRoutes)

Main routes

RouterModule.forRoot(appRoutes, { enableTracing: true })

Router tracing gives me no errors and correct urlAfterRedirects on NavigationEnd event.

Just to anyone who will meet the same problem.
If you have hybrid AngularJS to Angular app you have to keep old $locationProvider settings like $locationProvider.html5Mode({ enabled: true, requireBase: false });
Otherwise your new Angular routing will meet this issue.

Or you can switch off Angular.js route manipulation with such a hack

$provide.decorator('$browser', ['$delegate', ($delegate) => {

    $delegate.onUrlChange = () => {};
    $delegate.url = () => {

        return '';

    };

    return $delegate;

}]);
