This happens because `display-buffer-use-some-window' tries the least
recently used window first.  If that window happens to be small ...

In any case this sounds like a more general problem with your setup so
maybe something like the following would help

(defun make-small-windows-softly-dedicated ()
  (walk-window-tree
   (lambda (window)
     (cond
      ((and (> (window-total-size window) 10)
            (eq (window-dedicated-p window) 'too-small))
       (set-window-dedicated-p window nil))
      ((and (<= (window-total-size window) 10)
            (not (window-dedicated-p window)))
       (set-window-dedicated-p window 'too-small))))))

(add-hook 'window-configuration-change-hook 
'make-small-windows-softly-dedicated)

replacing the "10" by a value of your choice.
