Steps to Reproduce

<colorbox/>

1. open the popup (colorpalette or colorpicker)
2. focus the hex input field
3. try to copy/paste/home/end

Current Result

most keys besides the allowed characters #0-9A-F have no effect on both inputs
copy/paste only possible via mouse rightclick

Expected Result

preserve default behavior of input control

Root Cause

doKeyDown stops most key events

Workaround

overide the doKetDown_ function to allow default key behavior
handle input sanitation in an onInput event handler
