Import suggestion breaks code with `#[cfg]`

Rust Enhanced Version

2.25.0

Operating system

Arch Linux

Steps to reproduce

1. Add this code:

#[cfg(unix)]
use std::os::unix::fs;

fn main() {
    let _ = stdout();

    #[cfg(unix)]
    {
        // Using unix specific stuff here.
        let _function = fs::chroot::<&str>;
    }
}

2. Save the file.
3. Click on the suggestion to import the function.
4. Arrive at this code:

#[cfg(unix)]
use std::io::stdout;
use std::os::unix::fs;

fn main() {
...

5. Code should now be incompatible with non-unix platforms, because cfg(unix) is not on top of the std::os::unix import.

Should this be thrown to upstream as a compiler diagnostic issue? Or does it belong here, considering that rust-enhanced assumes rustc tips are trustworthy?
