1. Open attached file (any csv, tsv file, >15 000 lines, 8 columns at least)
2. Select 5000 lines and try to paste to libreoffice calc.
3. Select >15000 lines and try to paste to libreoffice calc.


Actual Results:
2 - text pasted
3 - nothing happens

2 - text pasted
3 - text pasted


Reproducible: Always


User Profile Reset: Yes
