Setting TitleFontSize & CountFontSize in Tile is no longer working

[ghost]

What steps will reproduce this issue?

After upgrade from v1.2.4 to v1.3.0-ALPHA155.
Setting TitleFontSize & CountFontSize in Tile is no longer working.
e.g.

<controls:Tile Title="Finance" TitleFontSize="24" Background="Green" />

Or in samples TilesExample.xaml

<Style x:Key="LargeTileStyle" TargetType="Controls:Tile">
        <Setter Property="Height" Value="125" />
        <Setter Property="TitleFontSize" Value="12" />
        <Setter Property="Width" Value="300" />
</Style>

Expected outcome

It should work as v1.2.4.
Also in Tile's ControlTemplate:

Reverting from

FontSize="{TemplateBinding TitleFontSize}"

back to

FontSize="{Binding TitleFontSize, RelativeSource={RelativeSource TemplatedParent}}"

works as before.

I'm wondering why TemplateBinding is not working on TitleFontSize/CountFontSize.
Is TemplateBinding not supporting custom dependency property?
But Count is also a custom DP and works normally.

Environment

• MahApps.Metro v1.3.0-ALPHA155
• Windows 7 x64
• Visual Studio 2015
• .NET Framework 4.6.1

The properties had the wrong value types, so maybe {TemplateBinding xyz} tries matching exactly to the types...
