WinRT bug report - ListView with large dataset being clipped

Question

I think I've found a bug in the Windows store (WinRT 8.1) version of the ListView (I've not tried on windows phone).
When I create a page with a ListView and bind it to an ItemsSource with many items I find that as I start to scroll through these items the rendered ListViewItems will suddenly disappear as if they are hidden behind another control.
I have created a simple example to demonstrate the issue.  Create a blank Universal app and replace the contents of the MainPage.xaml and MainPage.xaml.cs of the Win8 app with the code below.  Build and run the code and use the mouse to drag the
scrollbar handle down to item 41351 and you will see that all items after that are not displayed.
This looks like a bug to me but what does everyone else think?
Does anyone know of a work-around?

I've noticed an annoying feature of the WinRT ListView and I've created a simple example to demonstrate the problem.
With the ListView I'm experiencing unwanted clipping where a lot of items are displayed.  In the following example the ListView works fine on the first 41350 items but after that you cannot see them.  They still seem to be there because you can
move the focus using the cursor keys, but you just cannot see them.
Does anyone know why this happens and if there's a work around or fix for it?
