[Bug] [iOS] CarouselView calculates the wrong size for its child at start

[vwensel]

Description

When starting the app, sometimes the calculation of the child of CarouselView is not done correctly.

The child of the CarouselView gets an oversized size, so that it exceeds the limits of the CarouselView and everything that goes beyond this limit is not displayed (is outside the specified size).

Steps to Reproduce

n/a (can not reproduce it for the test)

Expected Behavior

The child (StackLayout) should adapt to the CarouselView. For a width of 500 and height of 500, the child (StackLayout) should be set to 500x500.

Screenshot 1:

Actual Behavior

Does not adapt to the CarouselView layout. The child (StackLayout) gets an oversized size. With a width of 500 and height of 500, the child (StackLayout) gets a width of 1680 and a height of 1200.

Screenshot 2:

(File: CarouselViewLayout) Method: ConstrainTo - size is

1. W:1180, H: 820
2. W:500, H: 500 (orange box set by me)
3. W:1680, H: 1320 (what is this here?) (comes from see Screenshot 3)

Screenshot 3: (File: ItemsViewController) Method: CheckForEmptySource
