Broken Back-Button on posts with multiple YouTube embeds

Hi,

I have the following problem: on posts/pages with multiple YouTube embeds the browser’s back-button (i.e. get back to previous site) breaks. As you scroll down, the plugin seems to create a “back-point” at every video player. So when you press the back-button in your browser it doesn’t bring you to the previous site. Instead, it will reset the YouTube embeds and make them disappear one by one.
You can get back to the previous site, by pressing the back button one time for every YouTube embed that was loaded. So if you scroll to the bottom of a post with 10 embeds you’d have to press back 11 times to actually get back to where you were before. This is very very bad for usability.

Is there a fix for this?

Especially anything using Mozilla Firefox seems to glitch out. I have tested with the following browsers/devices (tested on https://ressio.github.io/lazy-load-xt/demo/youtube-iframe.htm):
