Rustdoc doesn't render all `impl Trait` details

[Nemo157]

Given a function definition

pub fn timeout<'a>(&'a mut self, duration: Duration) -> impl Future<Item=(), Error=!> + 'a

then this is currently (rustc 1.26.0-nightly (482a913fb 2018-03-25)) rendered as

There are two very important bits of information missing from this:

• The associated types of the Future trait
• The lifetime bound on the returned type

Hmm, I'm unable to reproduce this on the latest nightly -- can you provide a link to the complete code causing this?

(Will try the older nightly soon)

Ah, this also requires re-exporting from a facade crate. I can't show my original code, but here's a quick example that repros it: https://github.com/Nemo157/rust-lang-rust-issue-49373, in inner/struct.Timer.html it does show the details, but not in temp/struct.Timer.html (a re-export of the previous struct).
