Clippy does not find SAFETY comment in splitted line

[TriedAngle]

Summary

clippy is unable to find the the Safety comment when splitting the line, for example when using cargo fmt.

Lint Name

clippy::undocumented_unsafe_blocks

Reproducer

use std::borrow::Cow;
pub struct Id(Cow<'static, str>);

impl<'a> From<&'a str> for Id {
    fn from(s: &'a str) -> Self {
        // SAFETY: The caller guarantees that the source data (e.g., the source file)
        // stays in memory for the duration of the program or these objects' lifetime.
        let s_static: &'static str = 
            unsafe { std::mem::transmute::<&'a str, &'static str>(s) };

        Self(Cow::Borrowed(s_static))
    }
}

the clippy output (I am actually using a Macro)
