You understood correctly: I do not consider this a bug (tho it might be
purely accidental, as I suspect it is: it's likely the result of the
fact that the list of completion is removed by icomplete before
processing a command and re-added afterwards, and minibuffer-message
adds a 2s wait during the execution of the command, i.e. at a point in
time where icomplete's list is not displayed).
