Sending escape sequences directly from zsh and bypassing tmux results in the wrong cursor shape when switching between panes which no longer reflect the current zsh vi mode. When using ZTE compatible terminals tmux supports tracking cursor shape changes on a per pane basis using a suitable `terminal-override`, this allows zsh and vim to behave as if they are not operating in tmux and everything works as expected. However, so far I've not been able to reproduce this behaviour in iTerm2.
