Flickity Sync fail while freeScrolling

So i have two slider, which are working.

The first slider serves as "navigaton", the second slider is a "freescroll"-Slider.

When the second slider is scrolling in freescroll and i select a navigation element on top of the "freescroll slide" nothing happens. It just works when the "freescroll slider" settled.

How can it be done, if the free scroll slider is still sliding, and i click at a navigation slider element, that it will synchronize?

Here my Example:

Use the linked JSFiddle as the reproduction and inspect how the navigation and free-scrolling sliders are synchronized while the second slider is moving. Reproduce a navigation click before the free-scroll slider settles, then compare it with a click after settling; the work is done when both cases synchronize as requested.
