Why tab inactive content does`t unloaded?

[emejibka]

Test case;

1. Create drazablz control, bind itemssource to viewmodel collection
2. Create dataTemplate for type
3. Run app. Inactive tab content does not unloaded when I switch tab. TabControl from wpf unload components from inactive tab.

Yes, currently by design, as this can drastically slow things down as layout/measuring rendering processes kick in.

I actually doubt it is still true though. I'm using 2 different controls (TabControl with a non reloading feature and TabablzControl). TabablzControl is much more slower cause it unloads my viewmodels. I tried to plug the non reloading class in it but it wont work at all.
