Bug report

In the Spreadsheet, when users scroll horizontally to columns that are not initially visible, then activate Freeze Panes, the Spreadsheet scrollbar behave incorrectly

Reproduction of the problem

1. Open the Dojo - https://dojo.telerik.com/zYbZtYDR.
2. In the Spreadsheet, scroll horizontally to columns that are not initially visible.
3. Activate Freeze Panes.
4. Attempt to continue horizontal scrolling.

Current behavior

When Freeze Panes is activated after horizontal scrolling:

• The Spreadsheet snaps back to the first (leftmost) column, Column A.
• Horizontal scrolling becomes unusable.
• Users cannot navigate to the right-hand columns until Unfreeze Panes is selected.

Expected/desired behavior

• Activating Freeze Panes should retain the current horizontal scroll position.
• Horizontal navigation should remain fully available across all unfrozen columns.
• Freezing should not disable the internal Spreadsheet scrollbar or shift the viewport.
