RadzenDataGrid Keyboard Selection jumps when AllowVirtualization is enabled

[MartinStanz]

Describe the bug
When selecting a row in a RadzenDataGrid and AllowVirtualization is enabled and navigation is done with the Arrow Keys on the Keyboard, the selection (or highlighted item) will jump after many continuous Arrow Down clicks.

To Reproduce
Steps to reproduce the behavior:

1. Go to custom playground
2. Click on 'Run'
3. Click on any entry in the Grid
4. Move with the Arrow Key down on the Keyboard at least 10 times
5. The Highlighted row jumps to a different position - often even out of sight

Expected behavior
The Highlighted row should not jump, at least not out of sight.

Desktop (please complete the following information):

• OS: Windows 11
• Browser: Google Chrome
• Version 144.0.7559.133

Additional context
Apparently it has to do with LoadData and then the re-rendering of the table, because it will only jump after a new Console Log entry is written (when LoadData was called).
