[Bug]? line.tabs().foreach(function(tab) .. returns no tabs when only 1 tab?

This is my setup where no tabline is drawn when I have 1 tab:
Is there any way around this? It wasn't an issue with the old config when looping over tabs manually
  tabby.setup({
    line = function(line)
      return {
        {
          { " " .. icons.common.vim2 .. " ", hl = { bg = colours.tabbar_bg, fg = colours.icons_fg, style = "bold" } },
          line.sep("", { fg = colours.icons_bg, bg = colours.tabbar_bg, style = "bold" }, colours.tabbar_bg),
        },
        -- Windows in current tab
        (function()
