SplitButton changes behavior depending on VariantSize

Hello,

We mimic how Office renders controls like split buttons.  When I look at Office apps, they render the same as what our controls currently do.  Can you give a specific example of where you see differently?  For instance, the "Replace" button in Powerpoint's Home tab is a SplitButton in medium variant and the arrow is by itself.  The "Select" button right below it is a PopupButton instead.

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.

Thank you, we hadn't seen that usage kind before.  We will mark down the request for adding support for this layout kind.  In the meantime, you would have to use the large variant or retemplate the control (which isn't easy).
