GuiTextEditProfile fillColor property not working

The guiTextEditProfile in TGB 1.7 does not recognize the fillColor property. No matter what you set it to it remains white. Does anyone know if this is by design or not. The bitmap color is white but it seems like the fillColor should change to whatever color specified.

if(!isObject(myTextEditProfile)) new GuiControlProfile (myTextEditProfile)
{
   opaque = true;
   cursorColor= "200 200 200";
   //fillColor = "255 255 255";
   fillColor = "0 0 0";
   fillColorHL = "128 128 128";
   border = -2;
   bitmap = "game/data/images/textEdit";
   borderColor = "40 40 40 100";
   fontColor = "0 0 0";
   fontColorHL = "255 255 255";
   fontColorNA = "128 128 128";
   textOffset = "4 2";
   autoSizeWidth = false;
   autoSizeHeight = true;
   tab = true;
   canKeyFocus = true;
   fontType="Wee Bairn";
   fontSize = 32;     
};
