Error description

• If a layout DXL column specifies a canvas colour, other layout
  DXL columns to the left which do not specify a canvas colour
  will also have the colour changed.
  
  If more than one column specifies a canvas colour, the one
  located furthest to the right will dictate the colour of those
  which do not specify it.
  
  To recreate:
  
   - create 2 layout DXL columns in a module using the following
  code:
  
  Column 1 :
  
  '
  displayRich 'should have a white background'
  '
  
  Column 2 :
  
  '
  DBE canv = getCanvas
  if(!null canv)
  {
      realBackground(canv, realColor_Red)
      realColour(canv, realColor_Black)
      display 'Red Canvas'
  }
  '
  
   - ensure that the second column is positioned to the right of
  the first
   - observe the background colour of the first column, it should
  be white, not red
  
  Workaround:
  
   - explicity specify canvas colours in all layout columns
