code-snippet copy button covers content in top-right corner

When the first line of a code snippet extends the full length of the block (i.e. is the longest line in the snippet), the copy button hides the code in the top-right corner.

See http://spring.io/guides/gs/accessing-data-rest/ for several examples ([Ctrl+F] -X PATCH)

Perhaps the copy button can display only on mouse-over of the snippet, or perhaps display outside the snippet block.
