Issue description

The tooltips (keybinding hints) in the compact-bar plugin do not appear when the session is switched to TMUX mode. However, the tooltips function perfectly fine in other modes such as NORMAL, LOCKED, PANE, TAB, etc.

with default layout, tooltip in TMUX mode work fine.

Minimal reproduction

zellij -c config.kdl
ctrl b

config.kdl

show_startup_tips false
theme "iceberg-light"
default_layout "default"    // compact default
