Thank you for contacting us.
What happens here is that currently we are doing the navigation when the transition has ended and in your scenario the transition is interrupted before it has ended and the navigation is not executed at all. We are going to reevaluate our options here and see what we can do to achieve the desired behavior in your scenario as well. We'll let you know when the fix is ready.
I have added some Telerik points to your account for bringing this to our attention. Thank you.
