If QML ComboBox is closed through a timer (comboBox.visible = false) while the popup is open, the popup is not closed.

This happens with both controls 1 and controls 2 popups.

In controls 2 there is a workaround, setting focus = false in onVisibilityChanged slot of the ComboBox closes the popup. But this workaround doesn't work for controls 1.

onVisibleChanged: {
    comboBox.focus = false
}
