Indesign Publish Online - Youtube videos embedded on different pages playing while not being viewed

I embedded a number of youtube videos into my indesign file and published online. They are all on different pages and are set to autoplay. They also have "start" and "end" times on them. Everything is working perfectly, except that when I go to view the published document online, the videos randomly start to play when I'm not viewing the pages they are on. I can hear them and not see them, unless I find the page the video is playing from. I've tested this in Chrome and Safari and am running into the issue on both. Including a link to my document below. Has anyone else had this issue?
