Chrome Wayland  预编辑文本显示(preedit)功能不太正常

### Summary

Chrome Version 141.0.7390.107 (Official Build) (64-bit)
fcitx5 Version 5.1.14
ArchLinux
Chrome 最新版本貌似已经默认以 Wayland 模式启动，并且启用了 text-input-v3
fcitx5 默认 **在程序中显示预编辑文本** 是开启的，但是 Chrome 在这个情况下移动光标修改预编辑文本时，显示并没有变化

感觉大概率是 Chrome 的问题，看作者能不能确定一下。如果是的话，看能不能给 Chromium 提一下 issue 推进一下 fix。

### Steps to Reproduce

这里我实际上已经按了3次左方向键 ←

### Expected Behavior

切换到 x11 模式运行 Chrome

```bash
google-chrome-stable --ozone-platform=x11
```

一切工作正常

# Frontends setup:
The environment variable checked by this script only shows the environment under current shell. It is still possible that you did not set the environment to the whole graphic desktop session. You may inspect the actual environment variable of a certain process by using `xargs -0 -L1 /proc/$PID/environ` for a certain process that you find not working.

## Xim:
1.  `${XMODIFIERS}`:

    Environment variable XMODIFIERS is set to "@im=fcitx" correctly.
    Xim Server Name from Environment variable is fcitx.

2.  XIM_SERVERS on root window:

    **Xim server name: "ibus" is different from that set in the environment variable: "fcitx".**

## Qt:
1.  qt4 - `${QT4_IM_MODULE}`:

    Environment variable QT_IM_MODULE is set to "fcitx" correctly.

    **`fcitx5-qt4-immodule-probing` not found.**

2.  qt5 - `${QT_IM_MODULE}`:

    Environment variable QT_IM_MODULE is set to "fcitx" correctly.

    Using fcitx5-qt5-immodule-probing to check the actual im module to be used under current environment:



3.  qt6 - `${QT_IM_MODULE}`:

    Environment variable QT_IM_MODULE is set to "fcitx" correctly.

    Using fcitx5-qt6-immodule-probing to check the actual im module to be used under current environment:

        QT_QPA_PLATFORM=wayland
        QT_IM_MODULES="wayland;ibus"
        IM_MODULE_CLASSNAME=QtWaylandClient::QWaylandInputContext

4.  Qt IM module files:

    Found fcitx5 im module for qt: `/usr/lib/qt/plugins/platforminputcontexts/libfcitx5platforminputcontextplugin.so`.

    Found fcitx5 im module for qt6: `/usr/lib/qt6/plugins/platforminputcontexts/libfcitx5platforminputcontextplugin.so`.

    Following error may not be accurate because guessing Qt version from path depends on how your distribution packages Qt. It is not a critical error if you do not use any Qt application with certain version of Qt or you are using text-input support by Qt under Wayland.
    **Cannot find fcitx5 input method module for Qt4.**

## Gtk:
1.  gtk - `${GTK_IM_MODULE}`:
