Can setting MinHeight of a WPF control be a workaround for failing VirtualizingStackPanel.ExtendViewport?

Question

And if it is, what control would be the best bet? DataGrid that has the virtualization or something else? This happens very very rarely so trial and error is not an option. Portion of my xaml and converter used is in the end.

This happens sometimes (maybe 1/1000?) when DataGrid's itemssource (ICollectionView) is refreshed.
