The candidate list shown on top of the gnome on-screen keyboard should behave the same way. Always when the “normal” candidate list would disappear, the candidate list on top of the Gnome on-screen keyboard should disappear as well.
I don't think the preedit behaviors should be the same way betweenn ibus-kkc and ibus-anthy. I'm thinking if the preedit behaviors between languages should be the same way in OSK.
I confirmed MS-Windows 10 does not support IME in OSK yet and ibus-anthy follows the preedit behavior. Probably I will upgrade my Window 10 to 11 later.
Probably I think ibus core or engines can handle the behavior after I modify gnome-shell with a new API ibus_input_context_set_client_name() to switch the OSK and physical keyboards.
