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

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

Anyone has any ideas how to fix this?

I'm afraid no.

Too bad, no one has any ideas on how to fix this. If anyone's got a solution, please feel free to comment and I'll reopen!
