[Bug] Shapes: ArcSegment throwing on iOS, doing nothing on Android

[davidbritch]

Description

I'd expect the following code to work:

        <Path Stroke="Black">
                <Path.Data>
                    <PathGeometry>
                        <PathGeometry.Figures>
                            <PathFigureCollection>
                                <PathFigure StartPoint="10,100">
                                    <PathFigure.Segments>
                                        <PathSegmentCollection>
                                            <ArcSegment Size="100,50"
                                                        RotationAngle="45"
                                                        IsLargeArc="True"
                                                        SweepDirection="CounterClockwise"
                                                        Point="200,100" />
                                        </PathSegmentCollection>
                                    </PathFigure.Segments>
                                </PathFigure>
                            </PathFigureCollection>
                        </PathGeometry.Figures>
                    </PathGeometry>
                </Path.Data>
            </Path>

On iOS this throws a ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

On Android, nothing renders.

Steps to Reproduce

1. Run the attached sample.
2. Browse to the PathGeometry page.
3. Scroll down to "PathGeometry with an ArcSegment".

Expected Behavior

ArcSegment is drawn.

Actual Behavior

iOS: ArgumentOutOfRangeException
Android: Nothing drawn.

Basic Information

• Version with issue: 4.7.0.968
• IDE: VSMac 8.6.4
• Platform Target Frameworks:
  • iOS: 13.5
  • Android: API 28
