Could you please share the output of :set statusline? while on that symbol?

Very sorry for the delayed answer. I finally found the time to look into this.

I was able to reproduce:

Quick analysis:

" highlight = false
statusline=%#lualine_a_2_command# 󰀘 %#lualine_b_3_command#  main %<%#lualine_c_diff_added_command#   11 %#lualine_c_diff_modified_command# 13 %#lualine_c_diff_removed_command# 1 %#lualine_c_command#%=%#lualine_c_command#  lvim.colorscheme %#lualine_b_command#  13:26 %#lualine_z_progress_command# %P/%L
" highlight = true
statusline=%#lualine_a_2_command# 󰀘 %#lualine_b_3_command#  main %<%#lualine_c_diff_added_command#   11 %#lualine_c_diff_modified_command# 13 %#lualine_c_diff_removed_command# 1 %#lualine_c_command#%=%#NavicIconsString#  %*%#NavicText#lvim.colorscheme%* %#lualine_b_command#  13:26 %#lualine_z_progress_command# %P/%L

I think the issue is that the NavicIcons* highlight groups indirectly reset the background to NONE, whereas they should inherit the background value of the lualine section they are located in.

--> No background

I don't think there is a way to achieve this in the colorscheme. I have a feeling that this requires some integration between lualine and navic to dynamically adjust the background values of all NavicIcons* highlight groups based on the lualine section.

One example is lualine's LSP diagnostic component, which creates highlight groups on the fly during initialization.
The Git diff component—visible in the lualine section C in my screenshots—is initialized in the same manner (lualine_c_diff_added_*, lualine_c_diff_modified_*, etc.).

A few additional interesting code locations, for future reference: 1, 2, 3.

For the time being, the simplest workaround is to override NavicIcons* highlight groups using an autocmd as shown below. Simply add to your Neovim config:

-- Apply custom highlights on colorscheme change.
-- Must be declared before executing ':colorscheme'.
grpid = vim.api.nvim_create_augroup('custom_highlights_sonokai', {})
vim.api.nvim_create_autocmd('ColorScheme', {
  group = grpid,
  pattern = 'sonokai',
  callback = function()
    -- navic colors for lualine
    local config = vim.fn['sonokai#get_configuration']()
    local palette = vim.fn['sonokai#get_palette'](config.style, config.colors_override)
    local navic_bg = palette.bg1[1]

    local function set_hl(name, fg)
      vim.api.nvim_set_hl(0, name, { foreground = fg, background = navic_bg })
    end

    local function get_hl(name)
      return vim.api.nvim_get_hl_by_name(name, true).foreground
    end

    set_hl('NavicText', get_hl('Fg'))
    set_hl('NavicSeparator', get_hl('Grey'))
    for _, c in ipairs(vim.g.sonokai_lsp_kind_color) do
      set_hl('NavicIcons' .. c[1], get_hl(c[2]))
    end
  end
})

Result:

from sonokai.

Thank you for your detailed answer and help!

If turns out that navic had options for color correction, specially designed for it to be embedded into a statusline: https://github.com/SmiteshP/nvim-navic/blob/83dc174da915f9dbc9b51169e9b62a2e0d42b527/README.md?plain=1#L275-L281
