Just to make sure that is not a conflict with my other JS.
Do you have same issues?
1) Create page with many panopress
2) Click on any PP on the page (opening in fullscreen)
3) Close the PP.
4) Click on any other PP on the page
5) the this time, the first PP that I’ve click, the width and height style disappear,
Conclusion: the first thumbnail disappear (Element exists but the width and height style is not on the PP_(X))
I’m working on this issues but, just let me know if it’s a known issue
