将动态内容添加到ContentPresenter时，为什么没有应用某些字体？

Question

I have basic ContentPresenter that I'm adding dynamic content to:

<ContentPresenter x:Name="Presenter"
                  FontSize="16"
                  FontFamily="Consolas" />

If I'm adding content directly in the XAML file, like

<ContentPresenter x:Name="Presenter"
                  FontSize="16"
                  FontFamily="Consolas">
    <TextBlock Text="Some text" />
</ContentPresenter>

The TextBlock renders fine, with the font family Consolas .

If I add content dynamically in the code-behind, though

this.Presenter.Content = new TextBlock { Text = "Some Text" };

the font family is the default font of the system and not Consolas

BUT

If I use a ContentPresenter with the font set to eg Courier New

<ContentPresenter x:Name="Presenter"
                  FontSize="16"
                  FontFamily="Courier New" />

static and dynamically added content is rendered perfectly fine!
