I'm using Firefox dev, it overflows for me. Are you sure you didn't hover the earlier screenshot of the unhovered image inside the red square, as opposed to the image inside a codepen embed?
Definitely using codepen. I can manipulate the scaling and view the html and css windows and stuff. I'm not using the latest firefox version, but it's not like this is a new feature right?
