Describe the bug

I have bound the hjkl keys for different purposes. While which-key correctly displays the popup for h and l, it does not do so for j and k. I assume this may be related to the triggers_blacklist setting, so I added the following to my config:

{
  triggers_blacklist = {
    n = {},
    i = {},
    v = {},
  }
}

This does not seem to have an effect. I assume this may be because this setting is merged with the default rather than overwriting it.

Steps To Reproduce

Set the config to

{
'folke/which-key.nvim',
event = 'VeryLazy',
opts = {
triggers_blacklist = {
  n = {},
  i = {},
  v = {},
}
},
}

Add some example j and k keybindings and disable the default motions:

vim.keymap.set('n', 'jj', function() print('Hello from j') end, { desc = 'Say hello from j' })
vim.keymap.set('n', 'kk', function() print('Hello from k') end, { desc = 'Say hello from k' })
vim.keymap.set('n', 'j', '<nop>')
vim.keymap.set('n', 'k', '<nop>')

Press j or k and see that the which-key does not appear.

Expected Behavior

The which-key window appears when pressing j or k.
