When adding items into a collection bound to SFDataGrid that requires the grid to resize based on the
ColumnSizer="Auto", the grid does not actually resize correctly. I have attached an example. To verify run the sample and press the buttons across the top to add items. Add the first item, and the grid cuts off the last column. Add the second item and the grid stays the same size with the data in the last column cut off. Add the third item and the even more of the last column is cut off.
I am test in a UWP project.
