Youtube Embed Video bug? what am i missing?

So on the site im working on, i have implementeret 2 youtube videos on a static frontpage, the videos work like a charm.

But when going out of the youtube fullscreen feature my videos is entirely gone on the page, but you can hear the sounds of videos still playing in the background. The videos are back to normal when refreshing.

This is what i have in my text editor.
