Didn't know about that option, it seems to solve the problem at hand
indeed, thanks! Is there any particular reason why it isn't enabled for
terminals of height 1 by default?

For example:

--- readline-8.0.orig/readline.c        2018-07-17 20:06:16.000000000 +0200
+++ readline-8.0/readline.c     2019-11-20 09:56:01.747705314 +0100
@@ -1211,6 +1211,10 @@ readline_initialize_everything (void)
   /* Read in the init file. */
   rl_read_init_file ((char *)NULL);
 
+  if (_rl_screenheight == 1) {

   if (_rl_horizontal_scroll_mode && _rl_term_autowrap)
