Description tim.ahrentlov 2015-01-09 07:56:57 UTC 
On iOS, the CarouselPage visibly goes through all pages when it navigates to the current page upon receiving focus. 

To reproduce load and run attached project on iOS. The try this:

1. Swipe left until purple page is reached.
2. Press menu and choose detail 2.
3. Press menu and choose detail 1.

Notice the flickering "scrollto" effect as the CarouselPage animates it's way through the pages to the current purple page.

This bug has been present since 1.2.x

Android does not have this bug. I do not know about windows.
