Describe the bug
DataGridColumn .CellTemplate accepts and displays correctly when using a DataTemplate, but not when defining a DataTemplateSelector

Steps to reproduce the behavior:

1. Assign DataGridColumn .CellTemplate a DataTemplate, note that the cell displays correctly
2. Assign DataGridColumn .CellTemplate a DataTemplateSelector, note that the cell displays nothing and that OnSelectTemplate method is never called in the DataTemplateSelector

Expected behavior
Cell displays according to the DataTemplate value returned in the OnSelectTemplate method
