Large indent level when indent_markers is enable

[ya2s]

Description

The indent level is large when indent_markers is enable with folder_arrow.

Like the file tree on Github.com and neo-tree, it looks good to be indent at the arrow part

Neovim version

NVIM v0.8.0-dev-nightly-238-g1a655b71a

Operating system and version

macOS 12.4

Minimal config

require("nvim-tree").setup({
  open_on_tab = true,
  update_cwd = true,
  update_focused_file = {
    enable = true,
    update_cwd = true,
  },
  respect_buf_cwd = true,
  git = {
    enable = false,
  },
  renderer = {
    root_folder_modifier = ":t",
    icons = {
      padding = "  ",
      show = {
        file = true,
        folder = true,
        folder_arrow = true,
      },
    },
    indent_markers = {
      enable = true,
    },

That is working as intended.

You are welcome to attempt a change in behaviour. PRs are gratefully accepted.

The indentation level seems same with neo-tree.

github.com uses half width separator instead of double width separator in nvim-tree.

Maybe my explanation was bad.
The claim is that the indent line should appear below the arrow, not below the directory icon (except at the end of the directory).

That change may be possible. As stated earlier, PRs are gratefully accepted.

In neo-tree, it looks incorrect to me since there are indent markers that do not represent indent level under the arrows. Neo tree does show the right indent level under the folders.
