In pagebuilder 3, in a row with a video background, when I serve a video from a remote cdn, this is rendered in the html:
<source src="/http//96.126.97.197/images/icechips-fall4.mp4" type="video/mp4">
The absolute URL is not rendered.
It would be especially helpful when you fix this to allow the prefix // as well as http:// and htps://
All video backgrounds broke on my sites when I upgraded to PageBuilder 3.
