Avalonia VideoView opens video in new window in ItemsControl with custom DataTemplate

I have an ItemsControl with custom DataTemplate in which I have a VideoView. All works great until the moment, when Video should be displayed. For some reason it is displayed in a new window like here I don't clearly understand why does it happen because all seems to be correct. I created a small sample for easier investigation. But I am sorry in advance if this problem is on my or Avalonia's side.

Minimal project and steps to reproduce

Run App
Press Play button

What is the current bug behavior?

Video opens in new window

What is the expected correct behavior?

Video should open in the old one

Environment

OS: Windows 10
