Hi,
First off: Glad that you investigated, this has been bugging me.

Hm. rl_reset_screen_size() works well for me. rl_resize_terminal() not
so much. Apparently the reason for that is that rl_reset_screen_size()
doesn't set ignore_env to to true when calling
_rl_get_screen_size(). I've verified that just toggling that parameter
changes the behaviour.
What bugs me about that a bit is that _rl_sigwinch_resize_terminal()
sets ignore_env to true.
Greetings,
Andres Freund
