bug: Missing default bindings - dd and yy not shown in screen for d and y keys

[b4shful]

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)

NVIM v0.9.5

Operating system/version

Ubuntu 22.04

Describe the bug

The yy and dd default binds are not shown in the plugin.

I can reproduce it with the minimal init.lua given as a default in this template.

Steps To Reproduce

1. Open a document
2. Press y or d to open the WhichKey screen for these two keys.

Expected Behavior

When y pressed, one of the options should inform that if the next key is y then it will yank the current line (yy). Likewise when d is pressed, one of the options should inform that pressing d as the next key will delete the current line (dd).

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

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 = {

  -- add any other plugins here
}
