[iOS, Catalyst] BoxView in AbsoluteLayout does not return to default AutoSize for Height/Width after reset #31496
Description
Description
When a BoxView inside an AbsoluteLayout is defined with AutoSize for width and height, and later its bounds are changed to explicit values and then reset back to AutoSize, the reset fails on iOS. Its width and height remain fixed to the explicit values instead of recalculating back to the default AutoSize.

- Add a BoxView inside an AbsoluteLayout with AbsoluteLayout.LayoutBounds="0,0,AutoSize,AutoSize".
- Tap Change Bounds button to change Layoutbounds value.
- Tap Reset button and observe that Height and Width are not reset to AutoSize in iOS and Catalyst.

On iOS, the width and height remain stuck at the last explicitly set values.
