Const generic parameter following a comment gets corrupted

[yvt]

fn func_name<
    // AAAA
    const BBBB: usize,
    /* CCCC */
    const DDDD: usize,
>() {}

Playground Link

Output:

fn func_name<
    // AAAA
    const
    const BBBB: usize,
    /* CCCC */
    const
    const DDDD: usize,
>() {
}

We will need to update the rust AST to get the span of the const kw so the span of the generic param can be determined correctly.

Yes, it sounds like a good idea to update the AST.
