Vaadin 7.6.0 Grid editor error


i just updated to Vaadin 7.6.0 and i have a problem on grid editor.

When in the grid there is only one row (and height is 1), in edit mode, the row disappear (scroll down) and i only see Save, Cancel.

In the previus version Save, Cancel, went above grid header when the grid has only one row.

It’s a common problem?

Thank you.
