centerMode doesn't work properly with even amount of slides

[renbeko]

I wanna be able to select what item in a row will be active. centerMode makes active only the third item in a row, while I want to make the second item active 🥺

Here's the link to Codepen with the code. I'll be very glad if somebody will help me to fix this issue 😘 https://codepen.io/sergesonkin/pen/OJEpKbP
