I’ve come across this bug on a few of my websites, where any loading screens I’ve created (interactions that happen as the page is loading) just keep going when I preview the site. I’ve set these loading screens to disappear when the page finishes loading, and this actually works fine when I go to the live link. It just seems like the interaction for when a page has finished loading doesn’t trigger in preview mode.
Here is one of the sites it’s happening to:

Another one on a different account:
I’m using the latest version of Chrome and Mac OSX Sierra.
