Touching Slider on PopupView closes the view

I am using Vaadin 7.1.10

Put a slider on a PopupView and use the slider - works fine.
Now move the mouse away from the slider and back to it and use the slider again. The PopupView is closed as soon as you click the slider.

This happens in case of

setHideOnMouseOut(true)

as well as

setHideOnMouseOut(false)

How can I avoid this behavior so that the PopupView remains open until the mouse is moved out of the PopupView
 

The problem is that oce the slider is used it gains the focus so when you click the slider the next time the click happens on the slider and not anymore on the PopupView so it is closed.
As a workaround I set the focus on another component on the PopupView inside Slider's value-change listener.
