No idea what's happening, but I wouldn't leap to the conclusion that $PS2
is being displayed. Given the presence of the [ctrl-L] chars it's just as
likely that both chars are being sent to the shell. Possibly
bracketed-paste mode is enabled by the emacs shell mode. If you start the
shell, then in a different window strace it what appears in the trace when
you resize the window? Also, you might want to try the current development
version that you'll find at https://github.com/att/ast/
<https://github.com/att/ast/pull/1427>. It's easy to build if you're
willing to install Meson.
P.S., You might want to take a look at https://asciinema.org for capturing
terminal sessions for playback.
