box::help() not working as expected on re-exported modules, possible bug?

[mpettis]

box::help() is not working as I thought it would for re-exported modules. I will get as close to a reprex as I can, as I can't seem to get {reprex} to work with this code yet. Below is layout, important file contents, and code example of failure (and how I can get success):

Code that fails (and works):

> #;; module-help.R
> 
> #;; Does not work
> box::use(mymod = ../foo)
> mymod$hello("me")
[1] "me"
> tryCatch({
+     box::help(mymod$hello)
+ },
+ error=function(e) glue::glue("{e}"))
Error in box::help(mymod$hello): no documentation available for "hello" in module "../foo"

> 
> #;; This does work, last help command pops up help file.
> box::use(moddirect = ../foo/bar)
> moddirect$hello("me")
[1] "me"
> box::help(moddirect$hello)

Directory layout:

.
|-- R
|   `-- module-help.R
|-- box-pkg-demo.Rproj
`-- foo
    |-- __init__.R
    `-- bar.R

__init__.R contents:

#' @export
box::use(./bar[...])

bar.R contents:

#' hello
#'
#' Prints out argument.
#'
#' @param nm String.  Name
#'
#' @return Invisible string.
#' @export
hello = function(nm) {
    print(nm)
}

Yes, that’s a bug: #330. Unfortunately fixing it isn’t trivial, but it’s on my list.
