Ctrl-A scrolls spreadsheet to upper left

[Merlin04]

Describe the bug
When you press Ctrl-A, the spreadsheet scrolls to cell [0, 0].

Expected behavior
The spreadsheet should not scroll when Ctrl-A is pressed. This issue isn't that big of a deal but it's inconsistent with Google Sheets, and a goal of this project is to have very similar behavior to Google Sheets/Excel to make it more smooth to use.

Additional context
The issue is because pressing Ctrl-A calls setDragSelection, and there's a useEffect in Spreadsheet.tsx that will scroll to the second coordinate point in the dragSelection whenever the dragSelection array is updated. Fixing this will require modifying how that works.
