Url pointing to invalid methods in documentation of pointer type

It turns out that the pointer type is implemented twice: for impl<T> *const T and impl<T> *mut T. However, the index section contains links to the first implementation only, whereas methods from the second implementation have different href anchors:

For example, links from the index:
https://doc.rust-lang.org/nightly/std/primitive.pointer.html#method.is_null
https://doc.rust-lang.org/nightly/std/primitive.pointer.html#method.is_null

And actual anchors:
https://doc.rust-lang.org/nightly/std/primitive.pointer.html#method.is_null
https://doc.rust-lang.org/nightly/std/primitive.pointer.html#method.is_null-1

The same in stable version.

Possibly related to #24558.

And is it bad? It clearly states impl for *const T and impl for *mut T after all...

[pravic]

The second is_null (and other methods) in index (on the left, below Methods) still points to the first implementation. That's wrong.

Oh I see! Yes, it's an issue.
