Comment before a list element is changed to an end-of-line comment for a different element

(playground link)

Input:

fn hello() {
    let _slice = &[
        // First item
        0x0001,

        // Second item
        0x0002,
    ];
    two_arg_fn(
        // First arg
        1,
        
        // Second arg
        2,
    );
}

fn two_arg_fn(_x: u32, _y: u32) {}

Output:

fn hello() {
    let _slice = &[
        // First item
        0x0001, // Second item
        0x0002,
    ];
    two_arg_fn(
        // First arg
        1, // Second arg
        2,
    );
}

fn two_arg_fn(_x: u32, _y: u32) {}

Here the intent was to have a comment associated with the element on the following line, but rustfmt confusingly turned the comment for the second element into an end-of-line comment for the first element.

Reproduce the report with the linked Rust Playground example or the rustfmt 1.7.0-stable CLI. Add coverage for both the array and function-call examples, and verify that comments remain attached to the following elements rather than becoming end-of-line comments for preceding elements.
