TabControl bug with sorted DataGrid

* .NET Core Version: 3.1
* Windows version: Windows 10.0.17763
* Does the bug reproduce also in WPF for .NET Framework 4.8?: Yes

I think the TabControl has a bug-like behavior with sorted DataGrids.
If you have a TabControl using a DataTemplate that has DataGrids in it, and you sort a DataGrid column and try to edit a cell in that column, and then try to change tabs in the TabControl, the program crashes with a framework exception that seems impossible to catch beforehand.

I don't believe that this is a desired behavior. The DataGrid should just stop the sorting when tabs are changed, I think the easiest solution is to just remove the throw in the source code.

I have created a minimal repro here:

If anyone knows of another solution to this problem, please let me know.
