Description

When trying to enter the output i get this error, but after i dismiss it the cursor enter the output as normal.

If i comment out self.display_win.api.set_config({"footer": ""}) in outputbuffer.py the error goes away.

    def remove_window_footer(self) -> None:
        if self.display_win is not None:
            ...
            #self.display_win.api.set_config({"footer": ""})

Reproduction Steps

1. Evaluate Visual
2. Choose python3 kernel
3. Enter Output

vim.keymap.set("v", "<leader>mv", ":<C-u>MoltenEvaluateVisual<CR>gv",
  { silent = true, desc = "evaluate visual selection" })

vim.keymap.set("n", "<leader>mo", ":noautocmd MoltenEnterOutput<CR>",
  { silent = true, desc = "show/enter output" })

My config:

  use { 'benlubas/molten-nvim',
    config = function()
      vim.g.molten_image_provider = "image.nvim"
      vim.g.molten_enter_output_behavior = "open_and_enter"
      vim.g.molten_output_win_max_height = 40
      vim.g.molten_output_win_max_width = 80
      vim.g.molten_output_show_more = true
      vim.g.molten_output_virt_lines = true
      vim.g.molten_virt_text_output = true
      vim.g.molten_auto_open_output = false
    end,
  }

Expected Behavior

To not receive an error

[modestosrc]

changing vim.g.molten_output_show_more to false fixes it too

I was not running neovim 10.0+ as written in the README for g:molten_output_show_more
