[2.2.5] ColorMenu setColorPalete.setColors vertical colors truncated

I would like to display a color array of 222 items (19 rows, 12 columns per row)

While I am able to set the colorPalette to display 12 columns and specify a width of the menu to 300 pixels only 5 rows of 12 columns each are displayed. The remaining rows are truncated.

What must I do to display the remaining rows?

Code:
ColorMenu cMenu = new ColorMenu();
cMenu.getColorPalette().setColors(  new String[] {
Code:
"000000","000033","000066","000099","0000CC","0000FF",
"003300","003333","003366","003399","0033CC","0033FF", "006600","006633","006666","006699","0066CC","0066FF", "009900","009933","009966","009999","0099CC","0099FF", "00CC00","00CC33","00CC66","00CC99","00CCCC","00CCFF", "00FF00","00FF33","00FF66","00FF99","00FFCC","00FFFF", "330000","330033","330066","330099","3300CC","3300FF", "333300","333333","333366","333399","3333CC","3333FF", "336600","336633","336666","336699","3366CC","3366FF", "339900","339933","339966","339999","3399CC","3399FF", "33CC00","33CC33","33CC66","33CC99","33CCCC","33CCFF", "33FF00","33FF33","33FF66","33FF99","33FFCC","33FFFF", "660000","660033","660066","660099","6600CC","6600FF", "663300","663333","663366","663399","6633CC","6633FF", "666600","666633","666666","666699","6666CC","6666FF", "669900","669933","669966","669999","6699CC","6699FF", "66CC00","66CC33","66CC66","66CC99","66CCCC","66CCFF", "66FF00","66FF33","66FF66","66FF99","66FFCC","66FFFF", "990000","990033","990066","990099","9900CC","9900FF", "993300","993333","993366","993399","9933CC","9933FF", "996600","996633","996666","996699","9966CC","9966FF", "999900","999933","999966","999999","9999CC","9999FF", "99CC00","99CC33","99CC66","99CC99","99CCCC","99CCFF", "99FF00","99FF33","99FF66","99FF99","99FFCC","99FFFF", "CC0000","CC0033","CC0066","CC0099","CC00CC","CC00FF", "CC3300","CC3333","CC3366","CC3399","CC33CC","CC33FF", "CC6600","CC6633","CC6666","CC6699","CC66CC","CC66FF", "CC9900","CC9933","CC9966","CC9999","CC99CC","CC99FF", "CCCC00","CCCC33","CCCC66","CCCC99","CCCCCC","CCCCFF", "CCFF00","CCFF33","CCFF66","CCFF99","CCFFCC","CCFFFF", "FF0000","FF0033","FF0066","FF0099","FF00CC","FF00FF", "FF3300","FF3333","FF3366","FF3399","FF33CC","FF33FF", "FF6600","FF6633","FF6666","FF6699","FF66CC","FF66FF", "FF9900","FF9933","FF9966","FF9999","FF99CC","FF99FF", "FFCC00","FFCC33","FFCC66","FFCC99","FFCCCC","FFCCFF", "FFFF00","FFFF33","FFFF66","FFFF99","FFFFCC","FFFFFF" } );
cMenu.getColorPalette().setColumnCount(12);
cMenu.setWidth("300px");
cMenu.showAt( 15, 15);
