I can reproduce it very easily, both in Emacs 26 and 27.  I wonder how
come you couldn't.

I don't think it's a bug, though: that's how character echoing works
in Emacs.  It is even kinda-documented in the ELisp manual, under
read-event.

I've reopened the bug, but if people agree this is established and
documented (albeit perhaps surprising) behavior, I think it should be
closed as wontfix.

Thanks.
