1. $ export EDITOR=emacs; stty -echo; ksh
2. resize the terminal emulator (either vertically or horizontally)

In the screenshot, the first "not found" came from pressing RET after a
vertical resize.  The second "not found" came from typing "date RET"
after a horizontal resize.  The ">" characters appear during the
resizing.
