Windows/Quick: Programmatically removing focus of TextInput does not work with IME

To reproduce:

• Make sure you use japanese IME ( https://www.coscom.co.jp/learnjapanese801/install_ime.html )
• Run attached example and type numbers from numpad

-> Focus should be lost and blinking cursor become invisible, but that is not the case.

Code looks like

    TextInput {
...
        text: "1"
        onTextChanged: {
            if (text.length > 2) {
                focus = false;
            }
        }
....
