Items get redisplay in UWP platform

Hi Team,

I have found a strange issue “Items get rearranged while moving the focus towards label” while working with Carousel View in UWP platform.

In my scenario, I have customized a layout(named as CustomView) derived from Grid and arrange the N number of labels to the CustomView and layout it into the CarouselView. And loaded a Grid in the ContentPage, within the Grid I have arranged the CarouselView(Contains CustomView and its items) in 0th row and another Grid(Contains a Label with Text property as “GridLabel”) in 1st row.
Run the application in UWP platform(Desktop) with below PC specifications and follow the below steps to replicate the issue.
Step 1: Move the cursor on CustomView Item1 using mouse.
Step 2: Now, move the mouse down to the Grid Label (pointer should focus on the text) text.

Issue: Note that items get redisplay and the OnSizeAllocated method of CustomView gets triggered.

PC Specification:
Machine: Non touch screen monitor
OS : Windows 10 anniversary V1607

Xamarin Forms version: v2.3.3.180

Please note that issue gets replicated only in the computer with non-touch screen monitors and in the mentioned Windows OS. If you have a touch screen monitor this issue does not replicate and also the issue gets replicate only for the first time while deploying the application.

For your reference, we have attached the sample in the attachment.

Please let us know if you require any clarification.

CarouselView has been deprecated and will be replaced with https://github.com/xamarin/Xamarin.Forms/pull/853
