Scrollbar is disabled by splitter when ScrollView is used in SplitView

[boston 0]

I have ScrollView in SplitView. when the scrollbar showup, it does not respond to mouse drag because it is captured by splitter of SplitView. This make the ScrollView unusable. Currently the splitter mouse capture width is pretty wide and it totally covered scrollbar.

any suggestion.

here is the code:

import QtQuick 2.6
import QtQuick.Window 2.2
import QtQuick.Controls 1.4
import QtQuick.Layouts 1.1

SplitView {
anchors.fill: parent
orientation: Qt.Horizontal

ScrollView{
    height:200

  
    Rectangle {
        width: 200
        height:400
        Layout.maximumWidth: 400
        color: "lightblue"
        Text {
            text: "View 1"
            anchors.centerIn: parent
        }
    }
}
Rectangle {
    id: centerItem
    Layout.minimumWidth: 50
    Layout.fillWidth: true
    color: "lightgray"
    Text {
        text: "View 2"
        anchors.centerIn: parent
    }
}

}
