Copying doesn't work in floating window

[wojciech-kulik]

When using tmux and floating window, I can't copy anything using selection mode or mouse. The same works when I do that in a normal window. I'm using macOS 15.1 + kitty + tmux 3.5a + floax plugin.

My config (relevant part):

set -g prefix C-s
set -g mouse on
set -s escape-time 0
set -g focus-events on
set -g history-limit 50000
set -g display-time 4000

set -g mode-keys vi
set -g xterm-keys on
bind -T copy-mode-vi v send -X begin-selection
bind -T copy-mode-vi y send-keys -X copy-selection-and-cancel
