Pierre gave you the answer:

Tab already has a key binding (completion) that will be active when you
call readline. If you don't want that binding to be active, you either
need to override it (bind tab to self-insert) or ensure that it doesn't
get invoked (use ^V for quoted-insert as Pierre describes).
