[Bug]: Tabline hidden by interaction with scope.nvim

[TommyCox]

Is there an existing issue for this?

• [X] I have searched the existing issues

What happened?

While using scope.nvim for tab-scoped buffers and option always_show_bufferline = false, switching to a tab with one buffer hides the tabline.

What did you expect to happen?

BufferLine to stay/appear due to multiple tabs existing.

Config

LazyVim defaults + overrides.

LazyVim

{
  "akinsho/bufferline.nvim",
  event = "VeryLazy",
  keys = {
    { "<leader>bp", "<Cmd>BufferLineTogglePin<CR>", desc = "Toggle Pin" },
    { "<leader>bP", "<Cmd>BufferLineGroupClose ungrouped<CR>", desc = "Delete Non-Pinned Buffers" },
    { "<leader>bo", "<Cmd>BufferLineCloseOthers<CR>", desc = "Delete Other Buffers" },
    { "<leader>br", "<Cmd>BufferLineCloseRight<CR>", desc = "Delete Buffers to the Right" },
    { "<leader>bl", "<Cmd>BufferLineCloseLeft<CR>", desc = "Delete Buffers to the Left" },
    { "<S-h>", "<cmd>BufferLineCyclePrev<cr>", desc = "Prev Buffer" },
    { "<S-l>", "<cmd>BufferLineCycleNext<cr>", desc = "Next Buffer" },
    { "[b", "<cmd>BufferLineCyclePrev<cr>", desc = "Prev Buffer" },
    { "]b", "<cmd>BufferLineCycleNext<cr>", desc = "Next Buffer" },
    { "[B", "<cmd>BufferLineMovePrev<cr>", desc = "Move buffer prev" },
    { "]B", "<cmd>BufferLineMoveNext<cr>", desc = "Move buffer next" },
  },
  opts = {
    options = {
      -- stylua: ignore
      close_command = function(n) LazyVim.ui.bufremove(n) end,
      -- stylua: ignore
      right_mouse_command = function(n) LazyVim.ui.bufremove(n) end,
      diagnostics = "nvim_lsp",
      always_show_bufferline = false,
      diagnostics_indicator = function(_, _, diag)
        local icons = require("lazyvim.config").icons.diagnostics
        local ret = (diag.error and icons.Error .. diag.error .. " " or "")
          .. (diag.warning and icons.Warn .. diag.warning or "")
        return vim.trim(ret)
      end,
      offsets = {
        {
          filetype = "neo-tree",
          text = "Neo-tree",
          highlight = "Directory",
          text_align = "left",
        },
      },
      ---@param opts bufferline.IconFetcherOpts
      get_element_icon = function(opts)
        return LazyVim.config.icons.ft[opts.filetype]
      end,
    },
  },
  config = function(_, opts)
    require("bufferline").setup(opts)
    -- Fix bufferline when restoring a session
    vim.api.nvim_create_autocmd({ "BufAdd", "BufDelete" }, {
      callback = function()
        vim.schedule(function()
          pcall(nvim_bufferline)
        end)
      end,
    })
  end,
}

Overrides

return {
	"akinsho/bufferline.nvim",
	dependencies = { { "tiagovla/scope.nvim", config = true } },
}

Additional Information

Overriding with always_show_bufferline = true does not seem to prevent the problem.
