[WASM] `(Color)Animation.AutoReverse` not working #6027

Open stevozilik opened 3 years ago

stevozilik commented 3 years ago

Current behavior

AutoReverse is ignored

Expected behavior

AutoReverse plays the animation from End state back to Start state, as in UWP e.g.

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

Same code as your Animation Test https://github.com/unoplatform/uno/blob/master/src/SamplesApp/UITests.Shared/Windows_UI_Xaml_Media_Animation/ColorAnimation_Fill.xaml

but with:

<ColorAnimation AutoReverse="True"
        Duration="00:00:01"
    Storyboard.TargetName="TargetRectangle"
    Storyboard.TargetProperty="(Shape.Fill).(SolidColorBrush.Color)"
    From="Orange"
    To="Brown" />

Environment

- [ ] GTK (Linux)
