Use WPF DoubleAnimation multiple times (ReSharper shows error in XAML) - wpf

Question

I want to use a DoubleAnimation multiple times. Here the code:
<Window x:Class="Project.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Window.Resources>
<DoubleAnimation x:Key="LeftAnimation" Storyboard.TargetProperty="(Canvas.Left)" From="0" To="100" />
<DoubleAnimation x:Key="TopAnimation" Storyboard.TargetProperty="(Canvas.Top)" From="0" To="100" />
</Window.Resources>
<Window.Triggers>
<EventTrigger RoutedEvent="Window.Loaded">
<BeginStoryboard>
<Storyboard Storyboard.TargetName="AnimatedBorder1">
<StaticResourceExtension ResourceKey="LeftAnimation" />
</Storyboard>
</BeginStoryboard>
<BeginStoryboard>
<Storyboard Storyboard.TargetName="AnimatedBorder2">
<StaticResourceExtension ResourceKey="LeftAnimation" />
<StaticResourceExtension ResourceKey="TopAnimation" />
</Storyboard>
</BeginStoryboard>
</EventTrigger>
</Window.Triggers>
<Canvas>
<Border x:Name="AnimatedBorder1" Background="Blue" Width="20" Height="20" />
<Border x:Name="AnimatedBorder2" Background="Red" Width="20" Height="20" />
</Canvas>
</Window>
The code works fine, but ReSharper underlines LeftAnimation in line <StaticResourceExtension ResourceKey="LeftAnimation" /> and says: "Invalid resource type: expected type is 'TriggerCollection', actual type is 'DoubleAnimation'."
Is that really a problem or is this a bug in ReSharper (version 9.2)?

Here is an editted solution:
Resources:
<Window.Resources>
<TimelineCollection x:Key="TimelinesCollectionKey1">
<DoubleAnimation Storyboard.TargetProperty="(Canvas.Left)" From="0" To="100" />
</TimelineCollection>
<TimelineCollection x:Key="TimelinesCollectionKey2">
<DoubleAnimation Storyboard.TargetProperty="(Canvas.Top)" From="0" To="100" />
</TimelineCollection></Window.Resources>
Triggers:
<Window.Triggers>
<EventTrigger RoutedEvent="Window.Loaded">
<BeginStoryboard>
<Storyboard Storyboard.TargetName="AnimatedBorder1">
<!--<StaticResourceExtension ResourceKey="LeftAnimation" />-->
<Storyboard.Children>
<ParallelTimeline Children="{StaticResource TimelinesCollectionKey1}"></ParallelTimeline>
</Storyboard.Children>
</Storyboard>
</BeginStoryboard>
<BeginStoryboard>
<Storyboard Storyboard.TargetName="AnimatedBorder2">
<Storyboard.Children>
<ParallelTimeline Children="{StaticResource TimelinesCollectionKey1}"></ParallelTimeline>
<ParallelTimeline Children="{StaticResource TimelinesCollectionKey2}"></ParallelTimeline>
</Storyboard.Children>
</Storyboard>
</BeginStoryboard>
</EventTrigger></Window.Triggers>
Targets:
<Canvas>
<Border x:Name="AnimatedBorder1" Background="Blue" Width="20" Height="20" />
<Border x:Name="AnimatedBorder2" Background="Red" Width="20" Height="20" /></Canvas>
