QTableView: Word wrapping and resizing rows do not play along

I am using a QTableView with word wrapping enabled and rows configured to resize to content automatically.

The view does NOT update the row height when columns are manually resized in a way that a cell changes from single-line text to double-line text (or vice versa).

The following line works around the problem:

CHECK_TRUE(connect(ui->tableView->horizontalHeader(), SIGNAL(sectionResized(int, int,
int)), ui->tableView, SLOT(resizeRowsToContents())));

However it seems strange that the above does not work out of the box. Is that behavior a bug?
