Restore working directory in terminal windows when loading session

Question

While using :mksession feature, I found that it works well with files and netrw, but not so much with neovim terminal windows. The problem is that, for terminal, it never preserves working directory inside the shell, even if I :lcd before saving the session. It does restore working directory inside vim itself, but the shell directory is always the one that was specified when terminal was created.

I'm wondering if there's a way to work around this. I'm thinking about something like calling extra function after session restore to run cd getcwd() in every terminal window, but I'm not sure how to do it correctly.

I've managed to write something that achieves desired effect.

function! Terminal_cd()
        if &buftype == 'terminal'
                call chansend(b:terminal_job_id, 'NVIM= cd "' . getcwd() . "\"\<cr>")
        endif
endfunction

function! Terminal_restore()
        let curtab = tabpagenr()
        let curwin = winnr()
        tabdo windo call Terminal_cd()
        exec curtab . 'tabn'
        exec curwin . 'wincmd w'
endfunction

I call Terminal_restore() after sourcing the session file. Since I already have vim automatically change working directory along with the shell cd, this seems to be good enough. Unsetting NVIM during restore is done because it is used to detect nvim session and calls :lcd automatically from shell function.
