doc(cfg) doesn't work on glob reexports #96166
Description
I tried this code:
#![feature(doc_auto_cfg, doc_cfg)]
#[doc(inline)]
#[cfg(feature = "raw")]
pub use crate::raw::*;I expected to see this happen:
The doc_cfg note would appear on the reexported items.
Instead, this happened:
The doc_cfg note does not appear on glob reexported items. If items are reexported individually, the doc_cfg note does apply.
(My actual case has a #[cfg(feature = "raw") on a containing module, and then #[cfg(feature = "lib")] on the glob reexport. The cfg note for raw always appears, but "and lib" only appears for explicitly named items.)

This looks like #83428

This is likely the same root issue, but is a different expression of the issue; in #83428 the cfg is present for the source item as well, but I'm applying the cfg to just the reëxport.
