Error suggestion for E0027 (pattern missing field) contains erroneous comma

[mk12]

I tried this code:

https://play.rust-lang.org/?version=nightly&mode=debug&edition=2018&gist=4f2737c4c44adb53103b875e0b7044cd

struct Foo {
    x: i32,
    y: i32,
}

fn test(Foo {
    x,
}: Foo) {}

I expected to see this happen:

A suggestion to change x, to x, ..

Instead, this happened:

A suggestion to change x, to x, .., (note the extra comma!)

With the comma at the end, I get a parser error and a suggestion to remove the comma.
