Describe the bug
In scenarios when we dynamically add data to the beginning of the Grid, the component re-renders elements whose re-rendering can be skipped.

To Reproduce

1. Open this StackBlitz example
2. Click on the "add row to beginning" button

Expected behavior
The onUpdated method should not be called when adding a new row to the beginning of the Grid. Instead, if you open the browser's console, the result is that "updating..." is logged three times.
