rustdoc: intra-doc links to enum variant fields have incorrect HTML title attribute

[gifnksm]

rustdoc generates <a title="..."> for intra-doc links, but the titles for enum variant fields seem incorrect.

I tried this code:

Cargo.toml:

[package]
name = "test"
version = "0.1.0"
edition = "2024"

src/lib.rs:

//!
//! <!--
//! START
//! -->
//! [Enum::Variant::field]
//! <!--
//! END
//! -->
//!

/// This is an enum.
pub enum Enum {
    Variant { field: i32 }
}

Run the following commands:

$ cargo +nightly doc
$ sed -n '/START/,/END/p' target/doc/test/index.html

I expected to see this happen:

The generated title attribute is field test::Enum::Variant::field

Instead, this happened:

Generated title attribute is field test::Enum::field (Variant is missing)

$ sed -n '/START/,/END/p' target/doc/test/index.html
START
-->
<p><a href="enum.Enum.html#variant.Variant.field.field" title="field test::Enum::field">Enum::Variant::field</a></p>
<!--
END
