Lazy Loaded Video Causes Page Reload, Sort Of

Every time a video is lazy loaded on a page, that page is added again when I go to the browser ‘back’ button. For example, if I have 5 videos on the page and scroll down the page to load them, I have to hit the back button 6 times to get back to the previous page. In addition to that being an issue on its own, I wonder if it will mess with my analytics data. Any thoughts?

Thanks, Phil
