Truncated month/year in DatePicker

I spent about an hour reading the DatePicker template to figure this out.

As you can see, the month/year label is truncated. Even though it doesn't look like one, this control is a button. Searching through my styles (thank goodness I have them all in one place), I find this style...

<Style TargetType="{x:Type Button}">

    <Setter Property="Margin" Value="1"/>

    <Setter Property="HorizontalAlignment" Value="Right"/>

    <Setter Property="Width" Value="100"/>

    <Setter Property="Height" Value="22"/>

</Style>

This sets the height of all buttons to 22 px by default, including the buttons in the date pickers.

• I could duplicate the DatePicker template and use a different style for this button. 
• I could give this style a key and explicitly reference it for all other buttons. 
• I could set the default height of all buttons to 25 px.

<Style TargetType="{x:Type Button}">

    <Setter Property="Margin" Value="1"/>

    <Setter Property="HorizontalAlignment" Value="Right"/>

    <Setter Property="Width" Value="100"/>

    <Setter Property="Height" Value="25"/>

</Style>
