Upon reattach, open nvim session gui shifts line blocks and scrolling with key input seems to rerender lines.

[nboaldin]

Reproduce bug:

1. Open zellij session with layout zellij -s this -l this.kdl

layout {
  cwd "/Users/code"
  tab name="nvim" focus=true {
    pane size=1 borderless=true {
      plugin location="zellij:tab-bar"
    }
    pane command="nvim" {
      args "."
        borderless true
    }
    pane size=2 borderless=true {
        plugin location="zellij:status-bar"
    }
  }
  tab name="server"  {
    pane size=1 borderless=true {
      plugin location="zellij:tab-bar"
    }
    pane {
        borderless true
    }
    pane size=2 borderless=true {
        plugin location="zellij:status-bar"
    }
  }
}

2. open buffers in neovim
3. detach from session
4. reattach to session
5. scroll with j or k

I tried changing and removing buffer related plugins in neovim to no avail.
