How to disable Drawer dim?

[Dmitiy Tyugin]

I have a problem with disabling drawer dim (grey background that appears when drawer is open). Can I disable it fully somehow?

import QtQuick 2.7
import QtQuick.Controls 2.0

ApplicationWindow {
      id: window
      width: 1080/3
      height: 1920/3
      visible: true

      Drawer {
          id: drawer
          width: parent.width
          height: window.height*0.4
          edge: Qt.BottomEdge
          dragMargin: 20
          dim: false
          modal: false
          Rectangle{
              anchors.fill: parent
              color: "red"
          }
      }
  }

Seems a bug in Qt 5.7. Solution is update to 5.8
