“1 like” on newly liked image isn't clickable

What I did:

1. Find an image that no one has “liked” yet.
   
2. Go to its permalink /p/ page.
   
3. Click the “Like” button.
   
4. Observe that “0 Likes” in the sidebar changes to “1 Like.”
   
5. Click “1 Like” in the sidebar.

What I expected to happen:

The list of who liked the image to open as on images where someone has already liked the image.

What actually happened:

A sense of sadness suffuses you as you are forbidden from basking in your fashion-setting exceptionalism.
