Clipboard not working in kitty + mosh + tmux

[Luis Useche]

Hi!

When I connect remotely with `mosh`, open `tmux` and run `tmux load-buffer -w`, the text copy doesn't work as expected.

```
$ echo "oh no! It doesn't work" | tmux load-buffer -w -
$ tmux -V
tmux 3.3a
$ mosh --version
mosh 1.4.0 [build mosh 1.4.0]

$ uname -a

```

Things work as expected when using ssh. Any suggestions here? I tried the workaround in https://github.com/mobile-shell/mosh/pull/1054 and no luck. The workaround in https://sunaku.github.io/tmux-yank-osc52.html does work but it is cumbersome.

Thanks,

Luis
