EDIT(camelid): This is not an intra-doc links issue. See #80882 (comment).

I found a glitch in the std/core library docs. The docs for PartialEq contain this snippet:

/// This trait allows for partial equality, for types that do not have a full
/// equivalence relation. For example, in floating point numbers `NaN != NaN`,
/// so floating point types implement `PartialEq` but not [`Eq`].

At present, the Eq link has the wrong target, because rustdoc links it to the method eq instead.

I sent a PR that forces the correct linkage (#80864) for this instance, but perhaps rustdoc could be smarter here?

On that PR @jyn514 writes:

This is a bug in rustdoc for several reasons:

• It shouldn't treat identifiers as case-insensitive
• It should give a warning if the link is ambiguous
