    colorchooser: Do less in ::response
    
    Some people destroy their widgets in ::response, so trying
    to access dialog internals from the class handler that is
    running afterwards has the potential to cause problems.
    Instead, we can reset the ::show-editor property every
    time we map the dialog.
