Page scrolls to top after keyboard-only interaction (Copy + Edit via F2 + Enter) — observed in v4 and v5

A user experience issue in Jspreadsheet CE (tested on both v4 and v5) where the screen scrolls to the top unexpectedly during keyboard-only operations.

🔄 Steps to Reproduce
Navigate to a spreadsheet table with scrollable content.

1. Select a cell or a column
2. Press Ctrl+C to copy.
3. Press F2 to enter edit mode.
4. Press Enter to confirm the value.

🧪 Observed Behavior
After pressing Enter, the page scrolls to the top — which disrupts user focus and context.
No error appears in the console.

✅ Expected Behavior
The cell should update and focus should remain on the same row without affecting the scroll position.

🔍 Additional Notes
This issue appears only when using the keyboard (no mouse interaction involved).
Similar issues have been reported earlier:

We're currently unable to trace the exact cause but believe it's triggered internally during cell re-render or focus.

📦 Environment
Library: Jspreadsheet CE v4 & v5
Browser: Reproducible on latest Chrome

Is this a known regression? Any workaround or fix suggestion would be appreciated.

Reproduce the issue in a scrollable Jspreadsheet CE table on the latest Chrome using the Ctrl+C, F2, and Enter sequence, then compare keyboard-only behavior with mouse interaction. Review the related issue #980 and investigate the internal cell re-render or focus path. Done means the edited cell retains focus and row position without scrolling the page to the top in both v4 and v5.
