[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:

cMenu.getColorPalette().setColumnCount(12);
cMenu.setWidth("300px");

 

 
cMenu.showAt( 15, 15);
