vif/vaf not working in Lua code

[tmbdev]

Describe the bug
vaf/vif not working in Lua code

To Reproduce

1. install nvim-treesitter and nvim-treesitter-textobjects
2. load a .lua file
3. move cursor inside a Lua function definition
4. use vaf/vif to attempt to mark the function

Expected behavior
I expect the lines comprising the function to be selected. Instead, it just changes into visual mode

The following work, however:

• marking functions with vif/vaf in Python code works
• marking paragraphs with vip/vap in Lua code works
• :InspectTree shows that the function is properly recognized by the parser

Output of :checkhealth nvim-treesitter

==============================================================================
nvim-treesitter: require("nvim-treesitter.health").check()

Installation ~

• OK tree-sitter found 0.23.0 (parser generator, only needed for :TSInstallFromGrammar)
• OK node found v18.20.4 (only needed for :TSInstallFromGrammar)
• OK git executable found.
• OK cc executable found. Selected from { vim.NIL, "cc", "gcc", "clang", "cl", "zig" }
  Version: Apple clang version 15.0.0 (clang-1500.3.9.4)
• OK Neovim was compiled with tree-sitter runtime ABI version 14 (required >=13). Parsers must be compatible with runtime ABI.

Additional context
I'm using this init.lua file with -u to isolate the problem, but I get the same problem with my full .lua file:

-- Packer setup to manage plugins
require('packer').startup({
  function(use)
    -- Packer manages itself
    use 'wbthomason/packer.nvim'

    -- Treesitter for syntax highlighting and textobjects
    use {
      'nvim-treesitter/nvim-treesitter',
      run = ':TSUpdate',
      config = function()
        require('nvim-treesitter.configs').setup {
          ensure_installed = { "lua" },  -- Install Lua parser
          highlight = { enable = true }, -- Enable syntax highlighting
          textobjects = { enable = true } -- Enable textobjects
        }
      end
    }

    -- Treesitter Textobjects support
    use 'nvim-treesitter/nvim-treesitter-textobjects'
  end,
  config = {
    auto_clean = false,  -- Disable automatic cleanup of unused plugins
  }

})

-- Basic Neovim settings
vim.opt.number = true             -- Show line numbers
vim.opt.relativenumber = true     -- Show relative line numbers
vim.opt.expandtab = true          -- Use spaces instead of tabs
