I am using youtube background video as headers on my pages. Each time I load a page, a mini youtube version of the video flashes on the upper left screen for 1 second. Is there a way to prevent this from happening? I don't remember this happening on other projects which I've used Youtube or Vimeo.

You can see a demo of this here: https://www.holyhoster.com/folium

This happens for each page, no matter if the page has already been loaded.

Hopefully there is some way to fix this.

Thanks.
