title: QT Text.WordWrap not working inside ColumnLayout
body: <p>I am developing application using QT QML. I am facing one strange issue with QML. I want to divide and display long text using QML. I am using <a href="http://doc.qt.io/qt-5/qml-qtquick-text.html" rel="noreferrer">QT Text</a> element to perform this task. I want to place this Text inside <a href="http://doc.qt.io/qt-5/qml-qtquick-layouts-columnlayout.html" rel="noreferrer">QT Columnlayout</a> with other UI elements. I am not able to display long text as Multi line text. Please help me to solve this problem. Here is my QML code.</p>
  
  <pre><code>import QtQuick 2.7
  import QtQuick.Controls 2.0
  import QtQuick.Layouts 1.0
  
  ApplicationWindow {
  visible: true
  width: 640
  height: 480
  title: qsTr("Hello World")
  color: "#18d28a"
  
      ColumnLayout{
          id: base_coloumn_layout
          width: parent.width
          Layout.margins: 10
  
          Text {
              id: application_instruction
              width: 640
              text: qsTr("xyxvx dgdgdh dhdgdd dhdgdhhgd dhhhdgd dhdgdg dhdgdh djhddh djddgdhgdh dhdgdhgdgh dhgdgdhj dhdgdghdg dhjdgdgd.")
              color: "#000000"
              font.pointSize: 12
              wrapMode: Text.WordWrap
          }
      }
  }
  </code></pre>
  
  <p>Same element is working properly when placed outside <code>ColoumnLayout</code>. I am able to display Text as multi line with code bellow. I want same code should work as Child of <code>ColoumnLayout</code>as there will be few more elements inside <code>ColoumnLayout</code>  </p>
