There's a bug in the behavior of the popup.  To see it:

1) reload the URL
2) click on the "?" link that's part of the code sample, see this text:

Form and function names in the code are hyperlinked to documentation, so click on them for more information.

To run the example, install Racket, start DrRacket, paste the example program into the top area in DrRacket, and click the Run button. Alternatively, save the program to a file and run racket on the file.

To run the example, install Racket, start DrRacket, and paste the example program into the top area in DrRacket. When a program in a Scribble language is opened in DrRacket, a Scribble HTML button appears for rendering the document to HTML. Click it.

... note the presence of *both* flavors of the last paragraph.

3) Click the ">" link repeatedly, until you get to the scribble example.  Once you're there, notice that the redundant paragraph vanishes.
4) Now, click the "<" link.  The redundant paragraph is gone!

This looks like an uninitialized Javascript variable to me.
