I did this in bash 5.2.15 (Debian 12 package version 5.2.15-2+b2) in
rxvt-unicode (Debian 12 package version 9.30-2+b4), and I can't see
whatever problem you're reporting. Typing a long command (one which
goes past the 80th column and scrolls the terminal's text upward) and
then backspacing all of it acts as expected. As does pressing up arrow
until a sufficiently long command is recalled from history.
Have you tried testing with several different terminal emulators? Be
sure to include xterm among them, as that one tends to be extremely
well-behaved in situations where the big fancy ones are not. I'm a fan
of rxvt or rxvt-unicode, which have both been kind to me, but good old
xterm should always be considered.
