`#[doc(inline)]` reexports have both duplicated docs and missing docs

[GuillaumeGomez]

Linked to #59368.

#[doc(hidden)]
pub fn bar() {}

/// Displayed
#[doc(inline)]
pub use	crate::bar as Bar;
#[doc(inline)]
/// Hello
pub use crate::Bar as Bar2;

Bar will have Displayed Displayed as documentation whereas Bar2 will have Hello Hello (but it should also have the docs from Bar).
