ContentDialog: Applying both Style and PrimaryButtonStyle - xaml

Question

Gang,
I'm referencing the 16299 version.
I'm trying to set a style for the ContentDialog, and a Style for the PrimaryButton. However, I cannot get both of them working together:
<ContentDialog x:Class="App1.ContentDialog1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
PrimaryButtonText="Button1"
SecondaryButtonText="Button2"
Style="{StaticResource ContentDialogStyle}"
PrimaryButtonStyle="{StaticResource ContentDialogPrimaryButtonStyle}">
<Grid />
</ContentDialog>
This will only apply the "Style" and not the "PrimaryButtonStyle". However, if I remove the "Style" attribute, I then get the PrimaryButtonStyle applied.
I have tried applying the PimaryButtonStyle inside the Style XAML, but that doesn't work either:
<Style TargetType="Button" x:Key="ContentDialogPrimaryButtonStyle">
<Setter Property="Template">
<Setter.Value>
...
</Setter.Value>
</Setter>
</Style>
<Style TargetType="ContentDialog" x:Key="ContentDialogStyle">
<Setter Property="PrimaryButtonStyle" Value="{StaticResource ContentDialogPrimaryButtonStyle}" />
<Setter Property="Template">
<Setter.Value>
...
</Setter.Value>
</Setter>
</Style>
Any ideas how I style the Primary/Secondary buttons inside a ContentDialog that itself has a Style?
Kind regards
Adam

It should be related with your Template in the ContentDialogStyle. We can change both ContentDialogStyle and PrimaryButtonStyle in the xaml, here is a simple example, you can see it. Then you should take a look at your Template in the ContentDialogStyle.
This is the code,
<Style TargetType="Button" x:Key="ContentDialogPrimaryButtonStyle">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate>
<Border BorderBrush="Green" BorderThickness="5">
<ContentPresenter Background="Red" />
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
<Style TargetType="ContentDialog" x:Key="ContentDialogStyle">
<Setter Property="Background" Value="Yellow"/>
</Style>
This is the ContentDialog,
<ContentDialog
...
PrimaryButtonText="Button1"
SecondaryButtonText="Button2"
Style="{StaticResource ContentDialogStyle}"
PrimaryButtonStyle="{StaticResource ContentDialogPrimaryButtonStyle}">
<Grid/>
</ContentDialog>
