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?
From Firefox 148 release notes for developers:[1]
> The overflow, overflow-x, and overflow-y CSS properties can now be used on replaced elements such as images, in the same way that they are used with other elements. Prior to this, replaced elements were always clipped to their bounding container. (Firefox bug 1999100).
