`add-load-path!` relative directory in Doom Emacs defaults to `~/.emacs.d/lisp` instead of ~/.doom.d/ where `config.el` sits

Question

As described in the title above, the following code in config.el:

(add-load-path! "lisp")

adds "home/user/.emacs.d/lisp/lisp" to load-path instead of "/home/sati/.doom.d/lisp" where config.el lives. This is contrary to the documentation of add-load-path! that says:

Add DIRS to load-path, relative to the current file. (emphasis mine)

Funny thing is, when I instrument it with edebug and run the code, it adds the correct path to the list.

Wonder what is going on here.
