0.10.0 commit 27fb629

Operating system/version

Ubuntu jammy 22.04 x86_64

Describe the bug

Anytime a key is pressed in normal mode, this error message appears :

Something went wrong:
...cal/share/nvim/lazy/which-key.nvim/lua/which-key/win.lua:97: title requires border to be set

I have a fix consisting of adding border = "none" to defaults at line 32 in lua/which-key/win.lua, but I don't know if the problem is on my side or if I should open a pull request.

Steps To Reproduce

Press a key that should display which-key window.

Expected Behavior

The which-key window is supposed to open normally.
