There are at least 4 problems evident in the above screenshot:
- There is no whitespace between the "Edit links" link and the "16 more" button.
- The arrow for the pop-up dialog doesn't line up with "16 more" button.
- There is no whitespace between the magnifying glass and the edge of the pop-up dialog.
- The pop-up dialog has a drop shadow but the arrow doesn't.
This screenshot was taken in Firefox 45, but it looks the same in Chrome and Safari. URL is https://en.wikipedia.org/wiki/Nadiya_Savchenko while logged in.
