Kakoune text editor starts with 'y' character in buffer

Further information

Background: kakoune is a vim-inspired text editor. You can tell it to run commands after it initializes with the -e flag:

kak -e 'exec i'

That command will launch kakoune, then run the exec i command, which is short for execute-keys i, which will virtually press the 'i' key, entering insert mode. The intent is that kakoune starts in insert mode instead of normal mode.

The issue is that when this command is run inside of zellij, it does start in insert mode, but a 'y' character is placed into the buffer. This occurs in every situation I have tested it in:

• tested in Kitty, Wezterm, and the native macOS Terminal
• tested in zsh, bash, and fish
• occurs whether executed at the command line, or run in a script
• tested with vanilla no-config zellij

Logs

zellij-13.log zellij.log

One line is jumping out at me, as the timing lines up for this being when I launch kakoune:

zellij.log:11:WARN   |zellij_server::panes::gri| 2024-08-11 11:14:18.206 [screen    ] [zellij-server/src/panes/grid.rs:3074]: Unhandled esc_dispatch: 61->[]

This unhandled escape code does not occur when launching kakoune without -e 'exec i'.
