"Start on Last Slide Viewed" Advances Slide

[mikesoltis]

When this option is not checked, everything works as it should. Upon returning to the page, the first slide is always displayed.

When this option is first checked: navigating from the slideshow page and then back again, the last slide I was viewing is displayed properly. However, on all subsequent returns to the page the slide showing is not the same as it was when i left the page - it appears to increment by 1 slide each time.

If I refresh the page or flush the cache while on the slideshow page, the next slide is displayed.

The view display is a block.

No errors on console, just this warning:

This continues to fail - it works for the first time back to the page - but subsequent returns to the page advance the slide by 1.

Here is a video showing the problem. The Timer Delay is set to 0, so the slides need to be advanced manually. The first part of the video is just toggling between the 2 slides leaving it on the 2nd slide. Click on "About" and come back to the slideshow. The same article is displayed (slide 2). So far so good. Hpwever, clicking on "About" and back a 2nd time, the slide is advanced (Slide 1). And each subsequent time, the slide is advanced by 1 (back and forth).
