Issue when grouping with a sorted column

Hello,

I have just updated from version 20.4.0.54 to 27.2.5, and I am encountering an issue with the SfDataGrid. The problem occurs when using the grouping feature of the SfDataGrid while sorting is enabled on another column. 

To reproduce the issue, you can use the attached code. Simply perform a grouping action on the Group column, then expand a group in the middle of the list. The exception shown below should be triggered. 

I also noticed that if you set EnableDataVirtualization to false, no exception is thrown, but the rows at the bottom start to disappear.


System.ArgumentOutOfRangeException: Index must be within the bounds of the List. (Parameter 'index')
