Back button click Android not registered in Qt Webview

I am creating a small Android application in Qt 5.10. The application consists of a main.qml that holds a Qt StackView. In this StackView one Qt Flickable page is defined with a button on it to navigate to a new page, which is a Qt WebView. After navigation, this WebView will load a local HTML page. But when I hit the Android back button on the second page the app will not navigate back to the first one. See the code below for more information.

main.qml

Code:

---

import QtQuick 2.10
import QtQuick.Controls 2.2
 
ApplicationWindow {
    id: appWindow
    visible: true
 
    StackView {
        id: navPane
        anchors.fill: parent
        initialItem: pageOne
 
        Keys.onBackPressed: {
            popOnePage()
        }
 
        function popOnePage() {
            if(navPane.depth == 1)
                return
            pop()
        }
 
        function pushOnePage(pageComponent) {
            push(pageComponent)
        }
    }
 
    Component {
        id: pageOne
        PageOne {}
    }
 
    Component {
        id: pageTwo
        PageTwo {}
    }
}

PageOne.qml

Code:

---

import QtQuick 2.10
import QtQuick.Controls 2.2
 
Flickable {
 
    Button {
        text: "Go to page 2"
        anchors.centerIn: parent
 
        onClicked: {
            navPane.pushOnePage(pageTwo)
        }
    }
}

---

PageTwo.qml

Code:

---

import QtQuick 2.10
import QtWebView 1.1
 
WebView {
    id: webView
    url: initialUrl //link to local HTML file
}

---

After some debugging I found out that the Keys.onBackPressed signal is never received. But when I use a Flickable instead of a WebView the signal will be received and the navigation works as expected. Can someone tell me if it is possible to receive this signal while using a WebView or maybe tell me what I am doing wrong? It will also do for me if there exists another component that can work with HTML. Any help would be greatly appreciated!
