QTableView::resizeRowsToContents() does not seem to be calculating the correct row height on Windows.

Here is an example which demonstrates this:
int main(int argc, char **argv)
{
QApplication a(argc, argv);

QStandardItemModel *model = new QStandardItemModel(5, 1);
for(int ii=0; ii<model->rowCount(); ++ii)

{ model->setData(model->index(ii,0), "one two three four five six seven eight nine ten one two three four five six seven eight nine ten"); }

QTableView tableview;
tableview.setModel(model);
tableview.resizeRowsToContents();
tableview.show();

return a.exec();
}

Notice (on Windows) that the row is too small for the text and thus the text is elided.

This does not seem to happen on X11 or Mac OSX.
