Jumping between nodes with LuaSnip is broken

[diniamo]

I have done the setup from the wiki regarding LuaSnip, however jumping between nodes doesn't work. I have also tested that luasnip.jumpable and luasnip.locally_jumpable always return false.

Note that I've also also tried with my confirm keymap simply being cmp.mapping.confirm({ select = true }), but it doesn' make a difference.

nvim-cmp configuration

cmp.setup({
  ["completion"] = { ["completeopt"] = "menu,menuone,noinsert" },
  ["formatting"] = { ["format"] = require("lspkind").cmp_format({ ["mode"] = "symbol_text" }) },
  ["mapping"] = {
    ["<C-Space>"] = cmp.mapping.complete(),
    ["<C-b>"] = cmp.mapping.scroll_docs(-4),
    ["<C-c>"] = cmp.mapping.abort(),
    ["<C-f>"] = cmp.mapping.scroll_docs(4),
    ["<CR>"] = cmp.mapping(function(fallback)
      if cmp.visible() then
        if luasnip.expandable() then
          luasnip.expand()
        else
          cmp.confirm({ select = true })
        end
      else
        fallback()
      end
    end),
    ["<S-Tab>"] = cmp.mapping(function(fallback)
      if cmp.visible() then
        cmp.select_prev_item()
      elseif luasnip.locally_jumpable(-1) then
        luasnip.jump(-1)
      else
        fallback()
      end
    end, { "i", "s" }),
    ["<Tab>"] = cmp.mapping(function(fallback)
      local has_words_before = function()
        local line, col = unpack(vim.api.nvim_win_get_cursor(0))
        return col ~= 0 and vim.api.nvim_buf_get_lines(0, line - 1, line, true)[1]:sub(col, col):match("%s") == nil
      end

      if cmp.visible() then
        cmp.select_next_item()
      elseif luasnip.locally_jumpable(1) then
        luasnip.jump(1)
      elseif has_words_before() then
        cmp.complete()
