When using the Fcitx5 Chinese input method in Electron applications to type text, the candidate box fails to display.

In applications like Chrome browser and Typora, when typing text, the candidate box cannot be displayed. After checking the background information of Fcitx5, it shows that the candidate box has been drawn. The developers of Fcitx5 helped me review the logs and said it might be a bug in elementary OS 8.
