📝 Provide detailed reproduction steps (if any)

1. Start selection in cell A
2. Drag to the left (to select e.g. 3 cells)
3. Drag back to the right to move the selection back to cell A.

✔️ Expected result

It should select that single cell A.

❌ Actual result

It keeps selection of a minimum of two cells.

📃 Other details

We need to fix the logic there. Right now we care fore "multi-range cell selections" but single-cell selections are fine too.

BONUS: Copy that selection of 2 cells and you get an error. Will automatically start working when we switch the logic to handle single-cell selections.
