@Waldo et al,
While working on another WIP site, I ran into the same problem! [bug caused by the EDITOR MODE perhaps??]
Here's what happened this time:
Everything was fine: interactions were smooth in preview and when published. I did this several times.
I opened the site in "Editor" and it loaded a bit oddly, with the interactions spazzing out. Published a change.
I logged out of "Editor" and opened the webpage in a new window...in incognito...republished and in a new window...still spazzing out.
So, I think this may have been what messed up my other interactions as well. Any thoughts as to how to fix this, or if it is a bug caused by the "Editor" mode?
