Qt Virtual Keyboard doesn't work with webengine in wayalnd

Steps to reproduce:

• compile and run pure-qml example (run it as described in https://doc.qt.io/qt-6/qtvirtualkeyboard-deployment-guide.html#using-qt-virtual-keyboard-with-qt-wayland )
• create a very simple qml application which uses WebEngineView (example provided below).
• run it as described in previous link (add -platform wayland)
• try to type something using on the duck's search line edit. On my computer the virtual keyboard gets closed immediately.

simple qml example:

import QtQuick
import QtQuick.Window
import QtWebEngine

Window {
    id: window
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")

    WebEngineView {
        id: webview
        url: "https://duckduckgo.com"
        anchors.fill: parent
    }
}
