Reproducer

https://godbolt.org/z/Wxde5d7f4

I tried this code:

// This line should avoid #14553.

// SAFETY: ...
mod x {}

// SAFETY: ...
#[doc(hidden)]
mod y {}

#[doc(hidden)]
// SAFETY: ...
mod z {}

I expected to see this happen: Three lints, for all safety comments.

Instead, this happened: The safety comment for y is not linted.
