rustdoc: "Copy item path to clipboard" includes "- Rust" in the middle

[9999years]

Code

The rustdoc "Copy item path to clipboard" button does the wrong thing.

Here: https://doc.rust-lang.org/stable/std/sync/atomic/struct.AtomicU64.html

I expected to see this happen: std::sync::atomic::AtomicU64 get copied to the clipboard

Instead, this happened: std::sync::atomic - Rust::AtomicU64 was copied to the clipboard

Version it worked on

It most recently worked on: Not sure, must have been working a couple months ago?
