--tmuxpane doesn't work

[Junxuan Liao]

Hi! I've tried to use --tmuxpane to view all commands in a single tmux 
window,

but it seems that it results in the same window configuration as --tmux 
flag.

My theory is tmux thinks all panes are already in window 1 when "joinp" 
is executed.


The command:

parallel --tmuxpane --fg "tmux display-message -p; sleep" ::: 100 100 100

shows:

source and target panes must be different
[p380670] 0:zsh, current pane 1 - (12:31 07-Oct-22)

in every window.

My tmux is at version 3.3a, and I have also experimented with older 
versions.

Can someone reproduce this? Thanks.
