IconifyByUnmapping some windows still iconified

.twmrc's IconifyByUnmapping definition with no parameters should result in all windows not showing a icon when f.iconify is triggered and for instance should result in the windows name just appearing in Icon Manager alone. Mostly IconifyByUnmapping works correctly as intended however in a number of instances it doesn't and a desktop icon is shown for some windows when iconified.
Examples of programs where it doesn't work are geany when Help/About is selected and that help window is iconified (or when geany's Search window is iconified). Libre Office Help/About and iconify that window is another example of when a desktop icon is shown.
Given that other programs such as pcmanfm, galculator... etc do see their help/about or search windows correctly showing in icon manager and not showing a desktop icon as desired/intended, then likely this 'bug' isn't a X11/twm bug but rather non-standard/non-compliance by certain programs such as geany and Libre Office.
