undocumented_unsafe_blocks doesn't detect safety comment above associated constant

[ketsuban]

Summary

I make use of the voladdress crate which uses a pattern of "unsafe construction, safe use", but when I put a VolAddress in a constant clippy doesn't detect the safety comment I add above it.

Reproducer

I tried this code:

#![warn(clippy::undocumented_unsafe_block)]

use voladdress::{Safe, VolAddress};

struct Control(u16);

impl Control {
    // SAFETY: this is safe
    const REGISTER: VolAddress<Self, Safe, Safe> = unsafe { VolAddress::new(0x0400_0204) };
}

I expected to see this happen: no clippy warning

Instead, this happened: a clippy warning
