[BUG] Lag while in tmux via ssh

[funnell]

Describe the bug
When I copy text in emacs while in a tmux session on a remote machine connected via ssh, there is a ~2 second lag.
If I'm doing this outside of tmux, but still on the same remote machine, there is no lag at all.

To Reproduce
ssh to remote server
start or attach to existing tmux session
open file with text in emacs
copy text (try to move cursor while this is happening to notice lag)

** System Info (please complete the following information):**

• OS: Linux
• Emacs Version: 28.2
• Terminal program: iTerm2
• Any terminal multiplexers in play: Tmux
• Local or remote (over SSH): remote over SSH

Additional context
This may have nothing to do with Clipetty, and if so then please forgive me. However, I'm hoping someone might have some advice 😄 Thanks for the help and wonderful package!

The delay comes from the invocation of shell-command-to-string here:

clipetty/clipetty.el

Line 96 in 01b3904

(let ((tmux-ssh-tty (shell-command-to-string clipetty-tmux-ssh-tty)))

Possibly due to executing my shell's config file each time
