tmux switch-client does not always work inside a tmux popup

[Iduoad]

I am experimenting with sesh and television so I setup a tv channel for sesh and I started running it from tmux display-popup.

But it didn't always work, I started troubleshooting for the issue, and I was able to get tmux-client not to switch inside the popup.

When I do this, sometimes the tmux switch-client does not work.

for s in (tmux list-sessions -F '#{session_name}')
      set before (tmux list-clients -F '#{client_tty}=#{client_session}')
      tmux switch-client -t $s
      set after (tmux list-clients -F '#{client_tty}=#{client_session}')
      echo "-> $s"
      echo "   before: $before"
      echo "   after:  $after"
  end

The issue is kind this behavior is kind of random (it doesn't always fail). Does anyone know why is this the case?

Here is an demo with sesh and tv.
