Summary0003911: Random circles appear in Path with curves and StrokeDashArray
DescriptionI noticed that random circular patterns often appear inside a path that has cubic Bezier curves and stroke with dashes.
Sometimes these circles are empty, sometimes just look incorrect.

Changing TessellationMaxPixelError from HighQuality to anything else fixes the example I provided, but I haven't checked thoroughly for other cases. So it looks like some kind of numerical instability in certain conditions.

While I cannot say that this is a major issue, it is quite noticeable in some cases.
Steps To ReproduceAdd this to MainWindow.xaml in HelloWorld example:
        <Grid Background="Black">
            <Path Data="M100,0 c0,250 250,0 300,300"
                  Stroke="Red"
                  StrokeThickness="40"
                  StrokeDashArray="0.2 0.2">
            </Path>
        </Grid>
Observe the circular pattern in the upper-left side of the path.
