When I click on your two things happen: yes, a new tab opens showing the gif image on a black background. That's the known bug that DocJohn mentioned. But also, in the tab where I was before, the post that the icon links to appears at the top of the page. All I have to do is close the unwanted new tab.

I'm using Firefox (automatically updated to the latest version) in Windows XP. I don't know what happens in other browsers/systems.
