Neovim version (nvim -v)

0.9.5

Operating system/version

Linux Gentoo

Describe the bug

Settings the layout align to 'center' instead of the default value 'left', causes which-key to break and no longer pop up. I have searched for solution and even tried setting opts.win.col = 0.5, but this also did not work.

Steps To Reproduce

in my plugins.lua file (lazy package manager): { "folke/which-key.nvim", event = "VeryLazy", opts = { preset = 'modern', icons = { rules = false }, layout = { align = 'center '}, },

Expected Behavior

Should align the modules from the center.
