Can you help with a mockup for this, after we've updated the dropdown menu design?
1) Click [...] next to a message
2) Choose "Permalink"
Observed: A separate dialog appears where you can click the "Copy Link" button to copy the permalink.
1) Change "Permalink" menu option in [...] to "Copy Link"
2) Once you click "Copy Link", the permalink is copied to the clipboard. The [...] remains open but the "Copy Link" term changes to " Copied"
NOTE: If the browser doesn't allow you to directly copy to the clipboard (e.g. mobile browser), then show the "Copy Link" popup as before
