Flickity won't initiate

[Pentarou]

Hi, although technically a flickity issue, it happens in Prestashop.

I'm using a paid Prestashop theme with support, but lately, I'm not getting an answer to an issue with the Flickity product slider. Sometimes when I go to our webshop, Flickity doesn't work. The products are then placed under each other instead of next to each other and the product slider does not slide and is not draggable. In other words, sometimes Flickity won't initiate. It happens on any browser, but more often in Firefox. On the first visit, it sometimes works, but when I go to a product page and go back to the homepage, the product slider stops working and I don't even see the div elements. I've made sure that all server and browser caches are creared and disabled.

To reproduct the problem:

1. Open Firefox (as this always happens in Firefox, but randomly in Chrome)
2. Go the the demo theme HERE
   As you can see, product slider works
3. Click on a product and go back to the homepage
   As you can see, product slider does not work

I have also reported this on github.

Our webshop is expected to open in July, can someone please help me solve this puzzle? Thank you very much!

I've already reported the issue on Flickity Github, but got no response, so any help is much appreciated!
