So I guess it also affects Emacs 30. To reproduce, put this in
test/lisp/emacs-lisp/ert-tests.el:

   (ert-deftest ert--pp-with-indentation-and-newline ()
     (should (equal '((:one "1" :three "3" :two "2")) '((:one "1")))))

Then run something like:

   $ make -C test \
     SELECTOR=ert--pp-with-indentation-and-newline \
     lisp/emacs-lisp/ert-tests.log

   Error: scan-error ("Containing expression ends prematurely" 221 221)

   Aborted: Ran 1 tests, 0 results as expected, 1 unexpected, -1 skipped
   
No idea if there's a deeper issue at play here, maybe something in
pp.el that a patch like the attached would just be papering over.
