Route params doesn't work when adding routes manually

[christian-ritter]

I have the following route:

/foo/:id

When I add this route manually as a breadcrumb then the route parameter doesn't get resolved.

I've tried it as follows:

this.breadcrumbs.store([{ label: 'foo', url: '/foo', params: ['123456'] }])
this.breadcrumbs.store([{ label: 'foo', url: '/foo', params: [{ id: '123456' }] }])
this.breadcrumbs.store([{ label: 'foo', url: '/foo', params: { id: '123456' } }])
this.breadcrumbs.store([{ label: 'foo', url: '/foo/', params: ['123456'] }])
this.breadcrumbs.store([{ label: 'foo', url: '/foo/', params: [{ id: '123456' }] }])
this.breadcrumbs.store([{ label: 'foo', url: '/foo/', params: { id: '123456' } }])
this.breadcrumbs.store([{ label: 'foo', url: '/foo/:id', params: ['123456'] }])
this.breadcrumbs.store([{ label: 'foo', url: '/foo/:id', params: [{ id: '123456' }] }])
this.breadcrumbs.store([{ label: 'foo', url: '/foo/:id', params: { id: '123456' } }])

It only works when I add the route parameter directly to the url:

this.breadcrumbs.store([{ label: 'foo', url: '/foo/123456', params: [] }])

But why do I need params then?
