MIT Blocks Import video is a dud

The alleged video in the second part of

http://ai2.appinventor.mit.edu/reference/other/download-pngs.html

is just a static image for me, on the Brave browser.

Does it move for you?

I am using Brave too. If I open the video in a new tab it plays. It doesn't play in Chrome or Firefox either. I am using Fedora Linux.

Confirmed.

Still a dud, compared to an animated gif.

Confirm only works if you open the "image" in a new tab, then video plays...

Chrome 135.0.7049.84 on Linux (Xubuntu 24.04)

The html(5) looks OK ?
