Commit `4afd483` breaks the color picker of ccc.nvim

[chrisgrieser]

Neovim version (nvim -v | head -n1)

NVIM v0.9.4

Operating system/version

macOS 14.1 (M1)

How to reproduce the issue

Using this minimal config:

for _, name in ipairs { "config", "data", "state", "cache" } do
    vim.env[("XDG_%s_HOME"):format(name:upper())] = "/tmp/nvim-debug/" .. name
end

--------------------------------------------------------------------------------

local plugins = {
    {
        "kevinhwang91/nvim-ufo",
        dependencies = "kevinhwang91/promise-async",
        commit = "4afd483", -- this commit introduced the bug
        -- commit = "068053c", -- this commit is still fine
        opts = true,
    },
    {
        "uga-rosa/ccc.nvim",
        init = function() vim.opt.termguicolors = true end,
    },
}

--------------------------------------------------------------------------------

local lazypath = vim.fn.stdpath("data") .. "/lazy/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",
        "--branch=stable",
        lazypath,
    }
end
vim.opt.runtimepath:prepend(lazypath)
require("lazy").setup(plugins)

1. Open a file with the config.
2. type something like local color = "#fff222"
3. Move the cursor to the color and run :CccPick

Expected behavior

Colors in the color picker should be displayed like this. (This is commit 068053c and before)

Actual behavior

The colors in the color picker are broken. This is the case since commit 4afd483.

---

Nothing else is broken, it is only this interaction between ufo and ccc. Since the break occurred due to a commit from ufo, I am suspecting that the problem lies on ufo's side rather than on ccc's side. (Nonetheless, I will also open a bug report at the ccc repo.)

Fix now, no idea why setl winhl-=CursorLine:UfoCursorFoldedLine clear ccc.nvim highlight.
