chinese input ibus candidates bar failed to display

when switch to iBus chinese character input method, the character candidates bar failed to display, it only shown the first candidate character with an underline, user unable to select other candidate character.
the ibus input method UI working as expected on other apps. only zapzap exhibits this behavior.

ZapZap: Version 6.0 (flatpak)
Distro: Fedora Linux 41 (64-bit Workstation Edition)
GNOME: ver 47
Windowing System: Wayland
chinese input: ibus-libpinyin ver 1.15.8

I believe it is something of the dictionary.

Take a test, in the Zapzap settings change the dicon folder to the Chrome dictionary located at:
/.config/google-chrome/Dictionaries

changed to ~/.config/google-chrome/Dictionaries but still the same.
