Go up a directory and close all folders

[swarn]

You can already hit backspace to move the root up a level. I want that, but with all folders closed after. I have a sort-of working version:

local my_up = function(state)
  require("neo-tree.sources.filesystem.commands").navigate_up(state)
  vim.defer_fn(function() neotree_zC(state) end, 100)
end

Where neotree_zC recursively closes folders, and is shown back in #445. Without delaying it via defer_fn, it doesn't work, so I assume there's an aync thing going on here. Is there a way to wait for navigate_up to complete, or otherwise avoid hacky "just wait a while" solutions?

I did something like this:

filesystem = {
  window = {
    mappings = {
      ["<BS>"] = "navigate_up_and_close",
    },
  },
  commands = {
    navigate_up_and_close = function(state)
      local fs = require("neo-tree.sources.filesystem")
      local utils = require("neo-tree.utils")
      local parent_path, _ = utils.split_path(state.path)
      if not utils.truthy(parent_path) then
        return
      end
      local path_to_reveal = nil
      local node = state.tree:get_node()
      if node then
        path_to_reveal = node:get_id()
      end
      if state.search_pattern then
        fs.reset_search(state, false)
      end
      fs._navigate_internal(state, parent_path, path_to_reveal, function()
        require("neo-tree.sources.common.commands").close_node(state)
      end , false)
    end
  },
}

Basically copy pasted the internal code for navigate_up changed the _navigate_internal since it has a callback, and I just run close_node as the callback.
