Layout measurement override of element ItemsRepeater should not return NaN values as its DesiredSize

[Valkirie]

Similar to Kinnara/ModernWpf#350, I get the above exception when I insert an item at index 0 to the collection that the ItemsRepeater is binded to.

Layout measurement override of element 'iNKORE.UI.WPF.Modern.Controls.ItemsRepeater' should not return NaN values as its DesiredSize.   at System.Windows.UIElement.Measure(Size availableSize)

Anyone has any ideas how to fix this?

I'm afraid no.
