      Description

      Have a simple program showing some text:

      #include <QApplication>
      #include <QLabel>
      
      int main(int argc, char *argv[])
      {
          QApplication a(argc, argv);
          QLabel l;
          // size doesn't matter, just makes it easier to see
          l.setText("<font size='7'>To</font>");
          l.show();
          return a.exec();
      }
      

      On Qt 5.3.2, it will look like this:

      On Qt 5.4.0, it will look like this instead:

      Note that the "o" is too far away from the "T".

      Kerning should be applied correctly. This worked in Qt 5.3.2.
