Current behavior

ezgif com-gif-maker(1)

Setting AutoReverse="True" does not reverse the animation.

<Storyboard RepeatBehavior="Forever"
		    AutoReverse="True">
	<DoubleAnimation Storyboard.TargetName="RectToAnimate"
				      Storyboard.TargetProperty="Opacity"
				      From="1"
				      To="0"
				      Duration="0:0:1" />
</Storyboard>

Expected behavior

The animation should be reverse what's set in the storyboard

autoreverse_expected

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

Workaround

Specify explicitly the inverted animation.

<DoubleAnimationUsingKeyFrames Storyboard.TargetName="RectToAnimate"
						        Storyboard.TargetProperty="Opacity">
	<LinearDoubleKeyFrame KeyTime="0:0:0"
					       Value="1" />

	<LinearDoubleKeyFrame KeyTime="0:0:1"
					       Value="0" />

	<LinearDoubleKeyFrame KeyTime="0:0:2"
					       Value="1" />
</DoubleAnimationUsingKeyFrames>

It's not yet implemented. It should produce a warning indicating that.
