white separator in NvimTree

Original comment: This somewhat broke my setup. There is now a white separator while I expect nothing/transparent. Or is this the intended result?

@ssiyad can you post your config?

require('tokyonight').setup({
    lualine_bold = true,
    style = 'night',
    terminal_colors = true,
    transparent = true,
    styles = {
        sidebars = 'transparent'
    }
})

Is this anyway related to https://github.com/neovim/neovim/pull/18581? I guess this is in effect an upstream issue (nvim/nvim-tree) and there is little tokyonight can do about it. Anyways, I created a PR which could be a nice compromise. Please check https://github.com/folke/tokyonight.nvim/pull/224
