When a website features an (embedded) video at the top and you need to scroll down to read the text unterneath the video:

If not disabled by your browser, the video playback starts. You stop the video. You beginn to scroll down to read the text unter the video, because you don’t want to watch the video. Now the video pops out and begins to play and hovers over the area where the text is displayed.

News websites are prone to this behavior.
