I have a DockSite bound to collection of view models. When the tabs are rendered, there appears to be a "border" at the top and bottom of the content of the tab. I've tried to set the Margin and Padding to 0 on the DockingWindow and TabbedMdiHost but it still appears. Refer to the image here:
Notice the dark blue border/gap between the "Service List" tab and the content. There is also one at the bottom of the content. If the tab loses focus, the color of that "gap" changes to a baby-blue color, so I assume there is some style setting or property for it. I either want to get rid of it or at least change the style so the color matches the background of my content.
