I put some messaging in that code, and it is indeed that bit that does
the resizing.

Here's a reproducer from emacs -Q:

(progn
  (setq display-buffer-alist '((".*" display-buffer-use-least-recent-window)))
  (pop-to-buffer "file1")
  (pop-to-buffer "file2")
  (split-window-below)
  (pop-to-buffer "file3"))

I end up with the following, and file3 in an oddly large window.
