It works fine for me. You need to drag it on the green lines. The problem is now getting rid of that video :/ can't drag it to trash.

Aha. That's a really narrow hit target. Yeah, it seems like if you place a video and decide you don't want it there after all or want it somewhere else, all you can do is delete the whole tab containing the video and start over. A work in progress, I suppose. :-)
