Re: SplitButton changes behavior depending on VariantSize

I am looking at the "Shape Fill" button in Powerpoint. I see that the text is with the dropdown arrow. In other words I can click on the text and the color picker shows up, you do not need to click on the small down arrow

So I wrote the following xaml

<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
</Grid.ColumnDefinitions>
<ribbon:SplitButton Label="Shape Fill1" Grid.Column="0" Height="25" Width="140" VariantSize="Medium" ImageSourceSmall="C:\\Users\\dvadmin\\Desktop\\MyIcons\\ShapeFill_16x16.png"></ribbon:SplitButton>
<ribbon:SplitButton Label="Shape Fill2" Grid.Column="1" Height="40" Width="100" VariantSize="Large" ImageSourceLarge="C:\\Users\\dvadmin\\Desktop\\MyIcons\\ShapeFill_32x32.png"></ribbon:SplitButton>
</Grid>

In the VarianSize= Large when user clicks on text the dropdown open, in case VariantSize=Medium it does not, the user needs to click on the small arrow.

In Powerpoint one can still click on the text and the dropdown opens.
