Accessibility: the "Copied to clipboard" message is not properly vocalized

I found the "Copied to Clipboard" message is not clearly displayed when the Copy button is clicked - the words overlap on top of each other. I guess this might be a related issue but this does not need the div out of a.

Attached is the screenshot and the patch fix!

The div out of the a is required by assistive technologies like Voice Over for proper vocalization (tested on Safari and Chrome).

But this change could probably require some CSS tweaks I guess.
