bug: which-key messes up nvim mode (shown in lualine)

[Susensio]

Did you check docs and existing issues?

• I have read all the which-key.nvim docs
• I have searched the existing issues of which-key.nvim
• I have searched the existing issues of plugins related to this issue

Neovim version (nvim -v)

0.9.4

Operating system/version

Debian trixie

Describe the bug

When using which-key for operator pending mappings, lualine mode won't show OP-PENDING.
As lualine is just calling vim.api.nvim_get_mode() https://github.com/nvim-lualine/lualine.nvim/blob/2248ef254d0a1488a72041cfb45ca9caada6d994/lua/lualine/utils/mode.lua#L47 I guess which-key popup is changing nvim mode inadvertently.

Steps To Reproduce

1. press d operator pending command
2. wait
3. which-key popup shows
4. nvim mode is NORMAL in lualine

if I enabled = false which-key

1. press d operator pending command
2. nvim mode is O-PENDING in lualine

Expected Behavior

It would be nice if popup would not change the underlying nvim mode.

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 = {
  "folke/tokyonight.nvim",
  { "folke/which-key.nvim", config = true },
  { "nvim-lualine/lualine.nvim", config = true },
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

vim.cmd.colorscheme("tokyonight")

That's to be expected, since you won't be in op-pending mode when which-key shows and becasue of redraws
