Rating control and scrolling

[tallichet]

I have a rating control (5 stars) in a FlipView with horizontal scrolling.

To reproduce:

1. Touch and hold 4th star
2. Move your finger to the left (up to the 3th Star)
3. lift your finger up.
4. tap the 2nd star

stars 1 and 2 are of the "Selected" color. => this is ok star 4 is of the "Selecting" color. => this is not ok.
