Qt.ImhNoPredictiveText not working on Android

Qt.ImhNoPredictiveText does not seem to disable keyboard suggestions. I have this field:

TextInput {
    id: edPassword
    Layout.alignment: Qt.AlignHCenter
    Layout.preferredWidth: 500
    Layout.preferredHeight: 120
    Layout.maximumWidth: parent.width
    echoMode: TextInput.Password
    inputMethodHints: Qt.ImhNoPredictiveText | Qt.ImhNoAutoUppercase | Qt.ImhSensitiveData
}

I tried many combinations, but none worked. I also tried the env variable QT_ANDROID_ENABLE_WORKAROUND_TO_DISABLE_PREDICTIVE_TEXT, but nothing changed.

I tested on:

• Android 14, Pixel 7a
• Android 9
• Android 10, Samsung Note9

On the Android 9 and Android 10 devices, echoMode also failed, and characters are visible until a space is added.
