Yes, that's the right behavior. See the end of the 2htdp/image docs

OK, it seems at odds with the note that freeze can "improve performance
without changing how the image draws," but I get that a square draws
larger than its bounding box so it gets cropped when frozen (or saved to
a file).
By the way, I think you can see this phenomenon in the rendering of the
2htdp/image docs. So for example, the section you referred me to has
this example:
(let* ([s (rectangle 20 20 "outline" "black")]
[r (beside s s s s s s)])
(above r r r r r r))
which when run in DrRacket produces a grid, but in the docs crops the
right and bottom lines. That makes the discussion about cropping very
confusing. Also: it seems you cannot in general have Scribble examples
that involve outlined shapes such that they look like they really appear
in DrRacket.
