Incorrect behavior of Drag.MaximumX if item is near maximum X

If you drag an item too close (5-10 px) of its maximum X (defined by drag.maximumX) and then release the mouse, you will not be able to drag it to the maximumX (unless you first drag the item away from the maximumX, and then drag the item to it).

The red rectangle in the screenshot cannot go thought its container (in blue). You will not be able to drag it to the right, unless you drag it first a tiny bit to the left.

The problem also occurs with minimumX.

This bug can easily be reproduced by downloading the zip file, or executing the following code :

import QtQuick 2.7
import QtQuick.Window 2.2

Window {
    visible: true
    width: 350; height: 50
    Rectangle {
        id: container
        width: 300; height: 50

        color: "blue"

        Rectangle {
            id: rect
            width: 50; height: 50
            color: (x >= 290 -width && x < 300-width) ? "red" : "green"

            MouseArea {
                anchors.fill: parent
                drag.target: rect
                drag.axis: Drag.XAxis
                drag.minimumX: 0
                drag.maximumX: container.width - rect.width
            }
        }
    }
}

• Try to move the green rectangle around (without releasing your mouse) to see that maximumX and minimumX are working as intended.
• Now move the green rectangle to the right until it turns red, release the mouse, and then try to drag it to the right.
