Fix the proposed patch since it had unexpected jumping effects in the fonts listbox.

For instance in wish (the extrafont package is supposed to have been installed):

tk fontchooser show  ; # shows existing fonts
package require extrafont
extrafont::load /home/francois/Téléchargements/Term-RegCcc.ttf
tk fontchooser show  ; # check that the new font family "Term" is now available in the listbox
# click on a font family _before_ "Term" -> fine
# click on a font family _after_ "Term" -> the font listbox jumped to the top of the list!
