Description:
CTRL-C copy or CTRL-V paste doesn't operate properly in Libre Office Calc running on Fedora 31. I've used Calc a lot in the past and don't recall this issue. Not sure when it appeared.

Steps to Reproduce:
1. Create a spreadsheet
2. Enter abc into cell A1, then def into A2
3. Click on A1 and type CTRL-C to copy
4. Click on A3 and type CTRL-V to paste <-- this works
5. Click on A2 and type CTRL-C to copy
6. Click on A4 and type CTRL-V to paste <-- this does NOT work

Actual Results:
Cell A4 ends up with some version of what's in A1 instead of a copy of A2

Expected Results:
A4 should hold what's in A2 (def)


Reproducible: Always
