Suggestion: only add Copy button where it makes sense

Whenever quoting code, even code that is meant to be replaced, the code block has an active Copy button. While you could make an argument that a reader might use the Copy button to prepare to paste the text into a search box, it’s far likelier in practice that the reader will copy the wrong code. This occasionally happens to me after a couple of hours of reading, and then I’m confused when the resulting code doesn’t behave. I wind up diffing my project directory against the final directory and trying to sort out what I missed. I’d suggest disabling the Copy button for reference code that we’re not adding to the project so that if I want to search on it, I have to select it and manually copy it.

@daviderb i have reached out to the people who who know if this is possible.
