Sorry, I tested with sources from April 12th which don't exhibit this
behavior yet.  What happens is that the minibuffer is now emptied by
this part

  (unless byte-compile--interactive
    (message nil))

in `byte-compile--message' which triggers a new resize when displaying
the next message.  Try with

(defun byte-compile--message (format &rest args)
  "Like `message', except sometimes don't print to minibuffer.
If the variable `byte-compile--interactive' is nil, the message
is not displayed on the minibuffer."
  (apply #'message format args))
