Ghostty "swallows" keybinds

[denisloch]

Possible Regression: Specific keybind no longer works in tmux

Working Version: 1.0.0 (public stable release)
Broken Version: 1.1.0 (stable channel)
Device: MacBook Pro 14" (M1) (likely not device-dependent)

I clear the ghostty console with the following config option:
keybind = ctrl+k=clear_screen

In my tmux config I have the following option:
bind -n C-k send-keys -R \; send-keys C-l \; clear-history

This setup allowed me to use Ctrl+K to clear the console in both Ghostty and tmux sessions.

However, since updating to version 1.1.0, tmux no longer receives the Ctrl+K keybind, suggesting that Ghostty is intercepting or "swallowing" it. This seems to be new behavior.

If any more information/clarification is required, feel free to ask!

Have a good day 😄
