FixedPage with UIElement & DataTemplates

I'm having some issues with FixedDocument & FixedPage content. I've found a work around that works for me, but I would much rather not have to use the work around. First off, I'm creating some FixedPage's from loaded UserControls (created from a loose xaml file). The Xaml files are basically template, and implement data binding.

Now, everything works mostly as expected. Except for one problematic template. This template uses an ItemsControl, a DataContext (provided in code at runtime), and a DataTemplate. This UserControl, when added to a FixedPage, works. t shows up as expected, with all the items in the ItemsControl according to the template. However, the DataTemplate has a Image in it. This Image is causing a null exception in LogicalTreeHelper.GetChildren() whenever the mouse moves over the image. The work around I used is to simply use a Rectangle with an ImageBrush to display the image. This is not ideal, because it places an odd restriction on the otherwise powerful WPF Xaml templates, and also the Rectangle does not scale to correct dimensions like a Image object can.

Anyway, the problem lies in that the FixedPage is trying to get the Logical Parent (as seen from looking at the symbols) of the Image. Which it does find a Grid item... but when trying to get the parent of the Grid, it is Null (whereas a normal Image not in the DataTemplate will have the top level control, and then the FixedPage as its grandparent). It seems that there is a problem with FixedPage's - or something that needs to be documented somewhere. Feedback is appreciated.

The stack trace is pretty big, but here it is:
