OSK not removed when active focus is no longer a text input

[Zsombor Egri]

Given the following example:
import QtQuick 2.0

Column {
    height: 400
    width: 400
    spacing: 10

    TextEdit {
        id: t1
        width: parent.width
        height: 40
    }

    Rectangle {
        width: parent.width
        height: 40

        color: "red"
        MouseArea {
            anchors.fill: parent
            onClicked: t1.focus = !t1.focus
        }
    }
}
When clicking on the red rectangle for the first time, t1 gets activeFocus set and the input panel appears. The second press on the rectangle sets t1 activeFocus to false but the input panel is not removed.
