bug: two underline at once for markdown

[rodhash]

Did you check existing issues?

• I have read all the tree-sitter docs if it relates to using the parser
• I have searched the existing issues

Tree-Sitter CLI Version, if relevant (output of tree-sitter --version)

tree-sitter 0.25.0 (18e4a2405b52ecd3cb9aefdd05d6554e76823473)

Describe the bug

It seems we have some integration bug between this parser and iTerm2.

After installilng this parser hyperlinks get a 2nd (dashed) underline and it looks quite weird:

notes:

1. In iTerm2 "Underline OSC 8 hyperlinks" is already disabled. This dashed underline shows up only in neovim w/ this parser installed.
2. This bug doesn't happen when using other terminals like Kitty.

Any idea how to disable this 2nd (dashed) underline?

As a workaround I'm disabling the parser for markdown files but this isn't ideal.

Nvim v0.11.0-dev-1028+g6dad1f9f1
iTerm 3.5.10

Thanks.

Steps To Reproduce/Bad Parse Tree

1. install markdown + this parser
2. open a MD file
3. To to a line with hyperlinks
4. You should see double underline

Expected Behavior/Parse Tree

No dobule underline (specially the dashed one)

Repro

-- DO NOT change the paths and don't remove the colorscheme
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({ "git", "clone", "--filter=blob:none", "https://github.com/folke/lazy.nvim.git", lazypath, })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  "nvim-treesitter/nvim-treesitter",
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})



require'nvim-treesitter.configs'.setup {
  -- A list of parser names, or "all" (the listed parsers MUST always be installed)
  ensure_installed = { "markdown", "markdown_inline" },

  -- Install parsers synchronously (only applied to `ensure_installed`)
  sync_install = false,

  -- Automatically install missing parsers when entering buffer
  -- Recommendation: set to false if you don't have `tree-sitter` CLI installed locally
  auto_install = true,


  ---- If you need to change the installation directory of the parsers (see -> Advanced Setup)
  -- parser_install_dir = "/some/path/to/store/parsers", -- Remember to run vim.opt.runtimepath:append("/some/path/to/store/parsers")!

  highlight = {
    enable = true,

    -- NOTE: these are the names of the parsers and not the filetype. (for example if you want to
    -- disable highlighting for the `tex` filetype, you need to include `latex` in this list as this is
    -- the name of the parser)
    -- list of language that will be disabled
    -- Or use a function for more flexibility, e.g. to disable slow treesitter highlight for large files
