Failure when a single line comment is placed between an attribute and a struct field

[luisfonsivevo]

Notice the mixed tabs and spaces, mixed brace styling, internal error message.

Input:

pub fn create_thing() -> Thing
{
	Thing
	{
		#[attribute]
		//this comment's presence breaks rustfmt
		
		field: 1,
	}
}

Output (rustfmt fmt_bug.rs):

error[internal]: left behind trailing whitespace
 --> fmt_bug.rs:6:6:1

warning: rustfmt has failed to format. See previous 1 errors.

pub fn create_thing() -> Thing {
    Thing
	{
		#[attribute]
		//this comment's presence breaks rustfmt
		
		field: 1,
	}
}

Expected:

pub fn create_thing() -> Thing {
    Thing {
        #[attribute]
        //this comment's presence breaks rustfmt
        field: 1,
    }
}

Removing the empty line with whitespace fixes the error message, but the output is still malformed in the same way:
Input:

pub fn create_thing() -> Thing
{
	Thing
	{
		#[attribute]
		//this comment's presence breaks rustfmt
		field: 1,
	}
}

Output:

pub fn create_thing() -> Thing {
    Thing
	{
		#[attribute]
		//this comment's presence breaks rustfmt
		field: 1,
	}
}

With the comment removed, braces are correctly relocated and the empty line is collapsed.
Input:

pub fn create_thing() -> Thing
{
	Thing
	{
		#[attribute]
		
		field: 1,
	}
}

Output:

pub fn create_thing() -> Thing {
    Thing {
        #[attribute]
        field: 1,
    }
}
