Rustfmt duplicate associated type bound in the presence of comment

[sgdxbc]

I tried this code:

trait Foo {
    type Bar<'a>: Baz1 // 
     where Self: 'a;
}

Run rustfmt

trait Foo {
    type Bar<'a>: Baz1
    : Baz1 //
    where
        Self: 'a;
}

Can reproduce without <'a>, but the code would be pointless in that case.

Somewhat related: comment is discarded

trait Foo {
    type Bar: Baz1 // what
    ;
}

Run rustfmt

trait Foo {
    type Bar: Baz1;
}
