Here is one with just the relevant segment
It still plays the entire video from the start here in the expando or when opening it in a new tab/window.
Weird. I've tested it in Brave, Firefox, Chrome, Edge, on Linux and Windows.
But I did see the problem you mentioned on an iphone. I think it's because safari on iphone doesn't let webpages render video themselves and instead pops the video out as a separate app running above the page, and manages the video element itself instead of letting javascript manage it. Dang. I might look to see if there is a way around this.
