Bug report

When the data in a Grid is filtered and grouped and then we try to add a new record an error is thrown

Reproduction of the problem

1. Open the Dojo example.
2. Filter a column (ex. filter ProductName that contains 'a')
3. Group by UnitPrice
4. Click the external 'add' button.

Current behavior

The following error appears in the broswer console: Uncaught TypeError: Cannot read properties of undefined (reading 'length')
The error appears no matter if dataSource.add() method or gridData.splice(0, 0, newData); is used

Expected/desired behavior

There should be no error when an item is added to the Grids dataSource

The issue is a regression starting with 2022.2.621
