… textarea Currently the clipboard service creates a temporary invisible `textarea` from which to copy the text into the clipboard, however since it only has `opacity: 0`, it has the potential of changing the layout in a noticeable way if it is present for longer. These changes add some extra styles to avoid changing the layout. I also did some small cleanup to make it a bit more robust.

No particular reason. I just wanted to make sure that it's off-screen so I put in something that is guaranteed to be large.
