<Line /> BackgroundColor does not change when it's DynamicResource value changes ?

[softlion]

I have this simple code to define a separator line in a CollectionView:

<Style TargetType="Line" x:Key="SeparatorLine">
     <Setter Property="HeightRequest" Value="1" />
     <Setter Property="BackgroundColor" Value="{DynamicResource LineColor}" />
</Style>

That I use like this:

<Line Style="{StaticResource SeparatorLine}" />

The LineColor is changing when the color theme is dynamically changed.

<Color x:Key="LineColor">#eeeeee</Color>
or
<Color x:Key="LineColor">#222</Color>

But the color of the line does not change.
I have other controls using the same system where the color is correctly changing.
Is that a bug in maui ?

It will also fail using the AppThemeBinding as well.

<Line HorizontalOptions="FillAndExpand" BackgroundColor="{AppThemeBinding Dark={StaticResource DarkSeparatorColor}, Light={StaticResource LightSeparatorColor}}" Margin="20,0,20,0" Grid.Row="2"/>
