quick glance at XAML in the generic.xaml, this is happening since I bind the image's height / width to the title.
Long story short, Valid bug. If you want to create a real bug on it, it is a real issue.
I think anything to correct it will cause a "breaking change" with quotes. Basically only real way i found to correct this is to put a Stretch="None" on the image. If anyone was expecting the prompt to do the resizing for them will have to create
an image to their sizing, it will fail. It looks like 26x26 is the proper sizing for the image.
Lemme play with this a bit more.
