Scenario to reproduce:
- Open "data/samples/CLUSTALW/COI.aln".
- Open "Statistics" options panel tab.
- Check "Show distances column" option.
- Set any sequence as reference.
Expected state: distances are calculated and shown. - Turn off "Automatic updating" option.
- Add a new sequence to the msa.
Expected state: the new sequence doesn't have a calculated distance, a '-' is shown in the distance column. - Turn on "Automatic updating" option.
Expected state: distances are recalculated.
Current state: the new sequence still has '-' as its distance.
