3. Add browser Window to main Window
4. Load any website with a simple password field ()

### Expected behavior

### Actual behavior

### Regression?

### Known Workarounds

n/a

### Does this problem also occur in the CEF Sample Application

Yes using WPF/OffScreen command line args

### Other information

Tryed with cef_binary_145.0.28+g51162e8+chromium-145.0.7632.160_windows64_client
Does **also** happen with cmd cefclient.exe --multi-threaded-message-loop --no-sandbox --off-screen-rendering-enabled --enable-gpu
Does **not** happen with cmd cefclient.exe --multi-threaded-message-loop --no-sandbox --use-alloy-style

Empieza reproduciendo el problema en la configuración WPF/OffScreen y con cefclient.exe usando --off-screen-rendering-enabled; después compáralo con --use-alloy-style, donde el problema no se produce. Investiga cómo se expone la entrada de contraseña al popup de Windows Chinese IME en la ruta de renderizado afectada. Se considera terminado cuando el texto de la contraseña ya no sea visible en el popup de IME, pero la introducción de la contraseña siga funcionando.
