Commented Issue: WP7 page transition error when resuming app [9465]

It looks like using the below combination of transition, caused some glitches to the pages, when u switch to the application, using the Mango multi tasking. Can easily be recreated in the sample that is provided with the toolkit.

(the one below, gives a turnstil effect that is not completed, as shown in 1.png)
<toolkit:TransitionService.NavigationInTransition>
<toolkit:NavigationInTransition>
<toolkit:NavigationInTransition.Backward>
<toolkit:TurnstileTransition Mode="BackwardIn"/>
</toolkit:NavigationInTransition.Backward>
<toolkit:NavigationInTransition.Forward>
<toolkit:SlideTransition Mode="SlideUpFadeIn"/>
</toolkit:NavigationInTransition.Forward>
</toolkit:NavigationInTransition>
</toolkit:TransitionService.NavigationInTransition>
<toolkit:TransitionService.NavigationOutTransition>
<toolkit:NavigationOutTransition>
<toolkit:NavigationOutTransition.Backward>
<toolkit:SlideTransition Mode="SlideDownFadeOut"/>
</toolkit:NavigationOutTransition.Backward>
<toolkit:NavigationOutTransition.Forward>
<toolkit:TurnstileTransition Mode="ForwardOut"/>
</toolkit:NavigationOutTransition.Forward>
</toolkit:NavigationOutTransition>
</toolkit:TransitionService.NavigationOutTransition>


(the one below, gives a slid up effect that is not completed, as shown in 2.png)
<toolkit:TransitionService.NavigationInTransition>

Adding
if (e.Uri.OriginalString == "app://external/" || !e.IsNavigationInitiator) return;
after FlipPresenters() didn’t work. I changed it
if (e.Uri.OriginalString == "app://external/" || !e.IsNavigationInitiator) return;
in order not to perform transitions either when navigating to or from external apps.
