      This is showing assistant without any High DPI auto scaling activated. It shows up now since previously QtWebKit always faked 96DPI which QTExtBrowser no longer does (so it is a regression of sorts). It does not show in Qt Creator since that sets Qt::AA_EnableHighDpiScaling (which could/should be done as a work around for Assistant as well).
      At any event, the font sizes in the style sheets should be adapted to Points.
