Copy image doesn't work

Hi,

i think Safari 8.0.4 has a "Copy Image" bug. Note: i don't talk about "Copy Image URL".

1. Open this image url https://pbs.twimg.com/media/CBkkNxcWgAACkJE.jpg:large in Safari
2. Select "Copy Image" from the context menu
3. Open Mail compose (in text mode - not formatted)
4. Try to CMD-V the image
5. -> you will see there URL to the picture

No take Chrome/Chromium and do the same -> you'll see the picture (see images after the post)

What's the purpose of "Copy Image"? It doesn't do anything different from "Copy Image URL".
