* We're somewhat trying to match Qt's behaviour here, as we want to ensure that
the items are always sized as if they have space for an icon when
ignoreIconSize() is true. In this case there's a +2 added "to avoid icons
overlapping" but only after the decorationsize is max'd with the font size. In
cases where the font is bigger than the icon, this is important.
