Description:
When you copy (or cut) a cell in Calc, the "ant" dashed line comes up but it appears like nothing is actually copied as you can't paste. If you copy a second time, the copy/paste works.

Steps to Reproduce:
1.Open Calc
2. Type "Test" in cell A1
3. Copy with Ctrl + C
4. Go to A2
5. Try to paste

Actual Results:
After copy you see the dashed ant line, but pasting does nothing. I attempted to paste into different application (Opera browser) and it didn't paste, assume the clipboard is empty despite the ctrl + c & ant dashed line

Expected Results:
Copy paste should work. I marked as minor because there's a "workaround" but it's pretty annoying. I believe this should be "minor - highest"


Reproducible: Sometimes
