QtQuick.Controls ComboBox popup shows at incorrect position when its containing window is on second monitor of a multi-monitor setup

When a QtQuick.Control ComboBox's popup menu is made visible while its containing window was made visible on the second visitor of a multi-monitor setup, the popup menu is shown at the incorrect position (at the rightmost edge of the 1st monitor).

The attached screenshot shows the issue.

I've attached a minimal example showing the issue. It is simply a qml file containing

import QtQuick 2.5
import QtQuick.Window 2.2
import QtQuick.Controls 1.4

Window {
	visible: true

	ComboBox {
		model: ["One", "Two", "Three"]
	}
}

Just make sure that the Window appears on the second visitor when initially shown, then click on the combobox to reproduce the issue.

It appears that any of the following 'fixes' the issue:

• Moving the Window after it was initially shown (but before opening the combobox)
• Opening the combobox a second time

Also note the warning:
