[Linux] `Path` is not clipping inside a ScrollViewer.

[ramezgerges]

Current behavior

In the repro below, scrolling the scrollviewer will make the Path inside remain visible even though it should be partially clipped. The shocking part is that this only happens on Linux. The WPF target on Windows clips accurately. Note that the repro seems to be very stable. I've tried a bunch of variations and they all repro 100% of the time.

The problem was originally discovered in SamplesApp (notice the unclipped chevron):

Expected behavior

The Path should only be visible within the viewport of the ScrollViewer.

How to reproduce it (as minimally and precisely as possible)

	<StackPanel>
		<Border Height="100" HorizontalAlignment="Stretch" Background="Blue" />
		<ScrollViewer Height="30">
			<StackPanel>
				<Path Data="m 0,0 c -0.639,0 -1.276,0.243 -1.765,0.729 -0.977,0.974 -0.98,2.557 -0.006,3.535 L 16.925,23.032 -1.768,41.725 c -0.976,0.976 -0.976,2.559 0,3.535 0.977,0.976 2.559,0.976 3.536,0 L 22.225,24.803 c 0.975,-0.975 0.976,-2.555 0.004,-3.532 L 1.771,0.736 C 1.283,0.245 0.642,0 0,0" Fill="Red" />
