Cursor position outside buffer error selecting custom text object in markdown files on branch `main`

[Bekaboo]

Describe the bug

Selecting around @block.outer with custom textobjects in queries/markdown/textobjects.scm makes nvim throw the following error:

E5108: Error executing lua: ...r-textobjects/lua/nvim-treesitter-textobjects/select.lua:32:
Cursor position outside buffer
stack traceback:
        [C]: in function 'nvim_win_set_cursor'
        ...r-textobjects/lua/nvim-treesitter-textobjects/select.lua:32: in function 'update_
selection'
        ...r-textobjects/lua/nvim-treesitter-textobjects/select.lua:174: in function 'sel'
        ....config/nvim/lua/configs/nvim-treesitter-textobjects.lua:34: in function <....con
fig/nvim/lua/configs/nvim-treesitter-textobjects.lua:34>

Put the following in queries/markdown/textobjects.scm in neovim config dir:

(fenced_code_block
  (code_fence_content) @block.inner) @block.outer

To Reproduce
Steps to reproduce the behavior:

1. Add keymap vim.keymap.set({ 'x', 'o' }, 'a.', function() require('nvim-treesitter-textobjects.select').select_textobject('@block.outer') end)
2. Create markdown file with a single non-empty code block:

   ```
   echo
   ```
   

3. Open the markdown file with neovim
4. Select around block with va.
5. See the error

Expected behavior

Should not throw error. The custom query works fine on master branch.
