Custom font family is not applied to Title and Content in ContentDialog

[luckypong]

Describe the bug

ContentControlThemeFontFamily has been added as a custom font, but it doesn't seem to apply to the ContentDialog's title and content.

All other styles are bound to a ThemeResource, but ContentDialog is bound to a StaticResource.

• Title: FontFamily
• Content: FontSize, FontFamily

Is this your intended style?

If you apply a custom style as a ThemeResource, the font will be set normally.

Steps to reproduce the bug

<FontFamily x:Key="ContentControlThemeFontFamily">ms-appx://</FontFamily>

Add and run

Expected behavior

ContentDialog must have a custom font applied.
