Templated control from a controls library appears cut off and with elevation.

I'm working on a controls UNO library. (Targets: Windows & Desktop)

I'm using this templated control:

<ControlTemplate TargetType="local:McKey">
  <Border x:Name="PART_Border"
          Background="{TemplateBinding Background}"
          BorderBrush="{TemplateBinding BorderBrush}"
          BorderThickness="{TemplateBinding BorderThickness}"
          Width="{TemplateBinding Width}"
          Height="{TemplateBinding Height}"
          CornerRadius="{TemplateBinding CornerRadius}"
          Margin="{TemplateBinding Margin}">

    <TextBlock x:Name="PART_Text"
                Foreground="{TemplateBinding Foreground}"
                FontFamily="{TemplateBinding FontFamily}"
                FontSize="{TemplateBinding FontSize}"
                HorizontalAlignment="Center"
                VerticalAlignment="Center" />
  </Border>
</ControlTemplate>

Initially it appears cut out, but it changes when you resize the window In the Desktop project, but it remains the same in the Windows project.

Even though it seems to have elevation compared to using directly the xaml code in the MainPage.

Otherwise, if I use a User Control instead of a templated control it appears correctly.
