rustdoc -- sidebar doesn't work in function documentation

[onur]

Sidebar is entirely empty and getting an error in console:

TypeError: sidebar is undefined main.js:1497:13

What browser are you using and at what version?

this is also specifically on the rand crate, or does it appear with other crates as well?

Firefox 58, rustc 1.26.0-nightly (322d7f7 2018-02-25) and rustc 1.26.0-nightly (3b8bd53 2018-03-03) and my docs.rs build rustc 1.26.0-dev (5c1d29a 2018-03-03)

This issue affects function documentation of any crate.

I think it comes from <script defer="" src="sidebar-items.js"></script>. Seems weird to have a path like this. I'll check what's wrong.
