The central slide does not work with the centerMode option

[Zebren]

short description of the bug / issue, provide more detail below.
An increase in the central slide using the .slick-center class works when the slider does not have more than 4 elements. When they become more than 5, the slider starts initializing the central class with a jerk. On my jsfiddle it is visually shown. The first slider works fine (it has no more than 4 elements), the second slider does not work (it has more than 4 elements, it works with interruption).
