Current Behavior

When a popup is positioned with an anchor the end of the screen (top-right, right), the popup is centered (usually correct), but because it's centered and the width of the popup expands beyond the window width, the popup gets cut off.

The previous behavior was to apply an offset so it fit inside of the window (correct).

Expected Behavior

Apply an offset to position of the popup so the popup content is always inside of the window

Steps To Reproduce

1. Create a button positioned with HorizontalOptions=End
2. Open a popup whose width is ~200 (example, but most widths demonstrate the issue)
3. Observe popup content gets cut off
