Unable to navigate with arrow keys to the bottom records of navigatable Grid with virtual scrolling and local datasource

[Dimitar-Goshev]

Bug report

Regression since 2022.1.119 . The last version navigating without issue is 2021.3.1207 - Dojo

Note: if the grid uses remote data, the issue is not reproducible - when more data is needed to be loaded, a loader is shown and after the data is loaded, scrolling down continues as expected - Dojo

Reproduction of the problem

1. Run the following Dojo
2. Click on the first record of the Grid - cell 1 in ID column - the cell is focused
3. Press and hold Down arrow key

Current behavior

The Grid starts scrolling down and focusing other cells. At some point the Grid stops scrolling down - it may happen on reaching different records, sometimes even on record 600+, sometimes on 46.
If we scroll the Grid, navigating downwards may continue.

Expected/desired behavior

The Grid starts scrolling down and focusing other cells until the last cell is reached and focused.
The last version navigating without issue is 2021.3.1207 - Dojo
