That is weird. I have the same behavior. I can not let this go. Why does :pub not “tab out” to :public? There must be a reason.
Update: I think I got it
Any module that is Application “kernel” or “stdlib” or “erts” will tab out.
Otherwise it will not.
:public_key is in its own “public_key” application.
Similarly, :pretty_pr, :os_sup and :release_handler will not tab out.
