QSyle draw VLine shaped frame on incorrect position

In qcommonstyle.cpp at lines 2271 - 2272 we have
p1 = QPoint(opt->rect.x()+opt->rect.width() / 2, 0);
p2 = QPoint(p1.x(), opt->rect.height());
must be:
p1 = QPoint(opt->rect.x()+opt->rect.width() / 2, opt->rect.y());
p2 = QPoint(p1.x(), p1.y()+opt->rect.height());
Improve it please in next release please!
