Expected behaviour

I also expect the component separators around the active buffer:

NORMAL > main > init.lua / test / testtttt / tessssstsssstssssst / fdgsdfgs / 54324354

                                           ^                     ^
                                           |                     |
                                           |                     |

Minimal config to reproduce the issue

require("lualine").setup({
    sections = {
        lualine_c = {
            {
                "buffers",
                component_separators = { left = "" },
            },
        },
})
