PathGeometry language parse problem

[dotMorten]

Describe the bug

I have a bunch of path geometries that I use for icons.
However quite a lot of them have weird rendering artifacts in WinUI, whereas they look just fine in WPF.

Steps to reproduce the bug

1. Add the following XAML to your WinUI and WPF apps:

<Path Data="M31.345 29H1.655L16.5 1.96zm-28-1h26.31L16.5 4.04z" Width="200" Height="200"
              Stretch="Uniform" Fill="Black" HorizontalAlignment="Center" VerticalAlignment="Center" />

2. Compare the generated output.

Reopening since the linked issue isn't marked as a bug.

I fixed that issue to be labelled as a bug rather than a question.
