yank_action copy-pipe set, but still exiting copy mode after selection

[kaushalruparel]

I am using tmux 3.2 and have set set -g @yank_action 'copy-pipe' in my conf, but after selection it still exits the copy mode. I am using similar configuration on tmux 2.7 on another host, where after setting set -g @yank_action 'copy-pipe' tmux remains in copy mode after selecting a bunch of text until I press q or Enter

I'd expect same behaviour between 2 tmux versions.
