Comment in trait visibility position causes token duplication

[miraclx]

Just noticed some weird behaviour, not sure if it's been reported already, I tried searching but I'm not sure how to classify it

this:

pub/* (crate) */ trait MyTrait {}

gets reformatted as:

pub trait MyTrait /* (crate) */ trait MyTrait {}

Test:

$ rustfmt <<< 'pub/* (crate) */ trait MyTrait {}'
pub trait MyTrait /* (crate) */ trait MyTrait {}

Worth noting, I didn't observe this behavior with structs, enums, unions and expanding the comment's scope to include the pub, it behaves correctly with this:

/* pub (crate) */ trait MyTrait {}

getting reformatted to:

/* pub (crate) */
trait MyTrait {}

Ah, this is similar enough to - #5841

@miraclx thanks for looking into this and finding #5841
