Bug description

When using the thumbnail navigation with the following configurations loop:true and effect:fade.

An issue occurs when navigating by first clicking the 2nd thumbnail and then the 3rd thumbnail.

It also happens when using click navigating from 3rd to 2nd thumbnail.

Expected Behavior

I expected no 'middle' image to pop up between navigation from clicking 2nd to 3rd thumbnail. Nor from clicking 3rd thumbnail and then the 2nd thumbnail.

Actual Behavior

It seems the slider quickly loops through the 1st image before actually ending on the 3rd image.

When I set loop:false the issue is gone.
