I seem to be unable to reproduce this, neither in Emacs 27.2 nor in
the current development sources.

What is the size (in lines) of your Emacs window that shows
quicklisp.lisp in this scenario?  That is, if you go to the beginning
of the buffer, what is the number of the last line visible on display?

I found a variant of this recipe where I do see the problem.  Stay
tuned.

Should be fixed now on the emacs-28 branch, please test.

Thanks.
