I have the following issues when there is a DataGrid inside RowDetails template

1. The + does not change to - after expanding the details

2. Clicking the header in the inner data grid of line 2 does not work (seems disabled)

3. Sometimes cannot edit the inner DataGrid. tapping 2 times on the cell does not enter in edit mode

On android and WinUI the DataGrid is enabled works fine, but on iOS while disable, it stills let me select, scroll, sort, edit data, etc.

When uprating the row details data, the data does not update in the UI. You have to resize the window, or collapse then expand the row details to see the updated value. 

The behavior happens in 7.0.0 version. In 6.8.0 it works as expected. 

When you have a business logic that is shared between several rows in RadDataGrid and ListenForNestedPropertyChange is set to true when you try to assign that object to one more row ArgumentException is thrown.
