The bullet icon color, graphical bullet color for the list and
the letter or number color for an ordered list are explicitly
set to black in ListPainter's drawIcon, drawShape, and drawLetter
methods. Thus <ol> list numbers and <ul> list icons do not pick up
color of the list text.
The idea of the fix is not to set color for the list item bullets,
so that their color equals to the list text color.
