Lazy loading with tabs - on open detail url - app is navigating to root of tabs

I need to have URL navigation (deeplinks) in my APP with tab-bar and I would like to use IonicPage for this, because I am using lazy loading too. So when I open some detail page, I see URL like this: http://localhost:8100/#/tabs/about/detail/2

but when I refresh the page, or when I open this URL in new tab, then URL is changed to home page tab http://localhost:8100/#/tabs/home/page-home and I see homepage screen.

Here is video in better resolution
Here is repo with this application

What am I doing wrong?
