Flip is not working on Firefox for initially hidden items

[devsuresh2005]

Hey Team,

First of all, thank you for the wonderful script which does an awesome job.

The flip is working fine except only one issue i.e., If an element is hidden on the initial page load then the flip is not working as expected at least in Firefox. My Firefox version 52.0.2 (32-bit). In my case, I have integrated the flip in a slider and the flip is working fine on first slide images but not on the upcoming slide images as those images were hidden on the initial page load :(

Here is an example http://allanalytics.com/ could you please extend your help here to resolve this issue? Please let me know if you need more details to reproduce this issue.

Thanks.
