How to reproduce the problem

Try to do :tabnew %

Expected behaviour

Open current file in active buffer in a new tab

Actual behaviour

Feels like a new "tab" is opened, but you can't see it in the tabline

Minimal config to reproduce the issue

  require('lualine').setup {
    sections = {
      lualine_a = { 'mode' },
      lualine_b = { 'branch' },
      lualine_c = { 'filename' },
      lualine_x = { 'encoding', 'fileformat', 'filetype' },
      lualine_y = { 'progress' },
      lualine_z = { 'location' },
    },
    tabline = {
      lualine_a = { 'buffers' },
      lualine_b = {},
      lualine_c = {},
      lualine_x = {},
      lualine_y = {},
      lualine_z = {},
    },
    extensions = { 'fugitive' },
  }
