Here’s one more scenarios, user is facing issue with Copy/paste on Windows 10 x64- Brave version 0.59.35

Steps to Reproduce:

1. Open a Google Spreadsheet in one tab (let’s call it tab A)
2. Open another Google Spreadsheet in another tab (let’s call it tab B)
3. Select a range of 3 cells in tab A and press Ctrl+C
4. Select one cell in tab B and press Ctrl+C
5. Go to tab A and press Ctrl+Shift+V

Actual Result: The pasted text is the copied from tab A in step 3
