Listgrid: freezing a column field validation tooltips disappear

[d.cavestro]

Usually when you edit a cell typing an invalid value and then leave the cell you can see an error icon: if you move the mouse over the icon a tooltip show the error message.

Problem: if you freeze a column the tooltip message is not available.

It seems reproducible in the data validation section of the showcase (SmartGWT 3.0), typing a non-numeric value in a "Population" cell then freezing another column (i.e. Country).
