That's not how it works. Supplements is a reverse dependency meaning that if
libreoffice-gnome package is installed, then ibus gets installed too. This is a
problem for two reasons:

1) ibus gets installed in all installations that have Libreoffice, (because KDE
also uses libreoffice-gnome, ibus-gtk is installed in KDE too). 
OTOH this also means that users who don't install Libreoffice, won't be getting
ibus which could also be a problem.

2) when someone uses the yast language module to install Chinese support, fcitx
is intalled. This is a problem because someone would end up with two IME
installed.

I think it would perhaps make more sense if ibus package "supplemented"
relevant  non-latin locale packages (e.g jp, ko, cn) instead or worked out
within the yast language module.
