Ellipsis on group if first column is frozen

Hi

I've a small issue concerning ellipsis on groups.

Repro case:
1. Go to http://www.smartclient.com/smartgwt/showcase/#grid_sort_sort
2. Freeze first column
3. Group by country
Result: an ellipsis is shown on the group name. Shouldn't the group name be fully visible in this case?

Thanks in advance!
Grts,
Wim
