Thank you for contacting us - indeed, the native tabstrips behave in the way you describe. Each tab maintains its own stack of views.
I am afraid that such behavior can't be accomplished with the current widget, as it would require a fundamentally different approach - each tab should have its own pane with a separate set of views associated. This would also affect the browser back button and history manipulation, to name a few things.
Given that, introducing such behavior to the current tabstrip widget would be a huge breaking change (the markup should be updated) - I think that at some point we may consider implementing this as an extension of the splitview (which maintains multiple panes), or as an entirely new widget.
