Steps to reproduce

-- setup defaults.pickers.live_grep where nui_hybrid_layout_fn is the hybrid layout in the recipes section:
...
          create_layout = require("utils.telescope_utils").nui_hybrid_layout_fn,
...
live_grep = {
          layout_strategy = "flex",
          layout_config = {
            horizontal = {
              size = {
                width = "90%",
                height = "90%",
              },
            },
            vertical = {
              size = {
                width = "90%",
                height = "90%",
              },
            },
          },
          hidden = true,
          only_sort_text = true,
          -- Handled in args
          use_regex = false,
          file_ignore_patterns = {},
          mappings = {
            i = {
              ["<M-l>"] = swap_regex_mode,
              ["<M-c>"] = swap_case_sensitive_mode,
              ["<M-x>"] = escape_regex_chars,
              ["<M-u>"] = refresh_picker,
              ["<M-r>"] = do_replace,
            },
            n = {
              ["<M-l>"] = swap_regex_mode,
              ["<M-c>"] = swap_case_sensitive_mode,
              ["<M-x>"] = escape_regex_chars,
              ["<M-u>"] = refresh_picker,
              ["<M-r>"] = do_replace,
            },
          },
        },
      },

Expected behavior

mappings should still apply

Actual behavior

they don't

Minimal config

where nui_hybrid_layout_fn is the hybrid layout in the recipes section

...
          create_layout = require("utils.telescope_utils").nui_hybrid_layout_fn,
...

```lua
        live_grep = {
          layout_strategy = "flex",
          layout_config = {
            horizontal = {
              size = {
                width = "90%",
                height = "90%",
              },
            },
            vertical = {
              size = {
                width = "90%",
                height = "90%",
              },
            },
          },
          hidden = true,
          only_sort_text = true,
          -- Handled in args
          use_regex = false,
          file_ignore_patterns = {},
          mappings = {
            i = {
              ["<M-l>"] = swap_regex_mode,
              ["<M-c>"] = swap_case_sensitive_mode,
              ["<M-x>"] = escape_regex_chars,
              ["<M-u>"] = refresh_picker,
              ["<M-r>"] = do_replace,
            },
            n = {
              ["<M-l>"] = swap_regex_mode,
              ["<M-c>"] = swap_case_sensitive_mode,
              ["<M-x>"] = escape_regex_chars,
              ["<M-u>"] = refresh_picker,
              ["<M-r>"] = do_replace,
            },
          },
        },
