ScrollView content offset shifts unexpectedly when FlowDirection is set to RightToLeft [iOS/MacCatalyst]

[ShyamSundar-SF4699]

Description

When a Grid contains a ScrollView with a HorizontalStackLayout inside, and the FlowDirection of the Grid is set to RightToLeft, the content inside the ScrollView gets shifted unexpectedly. The ScrollView itself has FlowDirection set to MatchParent. This causes the content offset to change automatically, which leads to the horizontal content appearing scrolled to the end or misaligned when switching to RTL.

Steps to Reproduce

1. Run the sample mentioned in the description.
2. Change the FlowDirection to RTL.
3. An offset appears in the ScrollView where no items are present.

Expected Result:

• Should be able to scroll through all items inside the HorizontalStackLayout within the ScrollView.

Actual Result:

• Offest makes some of the items in the HorizontalStackLayout away from the view.
