WebEngineeView and key handling

[mateusz.wojtkowski]

In code below I have WebEngineView and keys are handled in two ways - in second case, from dynamically loaded component.
Key handler does not work, in dynamically loaded component, when I am using WebEngineView.

web.qml

import QtQuick 2.0
import QtWebEngine 1.2
Item{
        id: root
        height: 500
        width: 500
        WebEngineView {
                id: manualWebView
                height: 500
                width: 500
                enabled: true
                url: "https://www.google.com/"
        }
 
        Keys.onReleased: {
                console.log("Loaded item captured INSIDE:",
                        event.text);
        }
 
        Loader {
                id: loader
                source: "debug.qml"
                focus: true
                onStatusChanged: {
                        if (loader.status == Loader.Ready) console.log('Loaded')
                        else
                        console.log("Status changed: "+loader.status )
                }
        }
}

import QtQuick 2.0
import QtWebEngine 1.2
Item{
        id: root
        height: 500
        width: 500
        WebEngineView {
                id: manualWebView
                height: 500
                width: 500
                enabled: true
                url: "https://www.google.com/"
        }

        Keys.onReleased: {
                console.log("Loaded item captured INSIDE:",
                        event.text);
        }

        Loader {
                id: loader
                source: "debug.qml"
                focus: true
                onStatusChanged: {
                        if (loader.status == Loader.Ready) console.log('Loaded')
                        else
                        console.log("Status changed: "+loader.status )
                }
        }
}

To copy to clipboard, switch view to plain text mode 

debug.qml

import QtQuick 2.0
Item {
    focus:true
    Keys.onReleased: {
                console.log("Loaded item captured OUTSIDE:",
                        event.text);
        }
}

import QtQuick 2.0
Item {
    focus:true
    Keys.onReleased: {
                console.log("Loaded item captured OUTSIDE:",
                        event.text);
        }
}

To copy to clipboard, switch view to plain text mode 

and output is:

$ qmlscene web.qml 
qml: Loaded
qml: Loaded item captured INSIDE: q
qml: Loaded item captured INSIDE: t

$ qmlscene web.qml 
qml: Loaded
qml: Loaded item captured INSIDE: q
qml: Loaded item captured INSIDE: t

To copy to clipboard, switch view to plain text mode 

Second handler(from loader) works properly when I remove WebEngineView.
Output after removing WebEngineView:

$ qmlscene web.qml 
qml: Loaded
qml: Loaded item captured OUTSIDE: q
qml: Loaded item captured INSIDE: q
qml: Loaded item captured OUTSIDE: t
qml: Loaded item captured INSIDE: t

$ qmlscene web.qml 
qml: Loaded
qml: Loaded item captured OUTSIDE: q
qml: Loaded item captured INSIDE: q
qml: Loaded item captured OUTSIDE: t
qml: Loaded item captured INSIDE: t

To copy to clipboard, switch view to plain text mode 

Why key handling does not work in dynamically loaded component when I am using WebEngineView ?
How can I solve it ?
