Package: Emacs
Version: 28.0.50

    % src/emacs -Q --eval '(setq max-mini-window-height 1)' -f icomplete-mode
    M-x a

at this point, you should presumably not see the "M-x a" in your
minibuffer window but only something of the form "{rp | lign | ..."

This is probably related to bug#24293 and bug#39379.
