Status bar disappears after webview fullscreen video in landscape mode

The iOS status bar disappears after viewing a fullscreen video from the WebView (e.g. YouTube) and switching to landscape mode while viewing. This does not happen when you stay in portrait mode while viewing, in this case the status bar is correctly shown again after closing the video.

Steps to reproduce:

1. Create empty Qt Quick Application

2. Add this code

import QtQuick 2.9
import QtQuick.Window 2.2
import QtWebView 1.1


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


  WebView {
    id: webview
    width: parent.width
    height: width * 0.5625
    anchors.verticalCenter: parent.verticalCenter
    visible: !loading
    url: "https://www.youtube.com/embed/CjyjEUFn_FI"
  }
}

3. Start video from WebView --> opens in fullscreen mode

4. Tilt device to go to landscape mode

5. Tilt back to portrait mode (or stay in landscape, both do not work)

6. Close video

7. Status bar is gone, status bar height is 0
