Increase visibility assist doesn't play well with comments

code snippet to reproduce:

use crate::internal::Foo;

pub mod internal {
    pub struct Foo {
        /// plz
        bar: u32,
        // plz
        baz: u32,
    }
}

pub fn add() -> Foo {
    Foo { bar: 42, baz: 42 }
}

Running increasing visibility assist on bar/baz produces this:

use crate::internal::Foo;

pub mod internal {
    pub struct Foo {
        pub(crate) /// plz
        bar: u32,
        pub(crate) // plz
        baz: u32,
    }
}

pub fn add() -> Foo {
    Foo { bar: 42, baz: 42 }
}

Which is not valid code. I like the idea though.

I didn't check if it was fixed in the most recent version, but I tried looking though tickets/MRs and found no matches.

Hello! the original code did not correctly handle possible comments and attributes when processing visibility, which led to adding visibility directly before AST nodes, resulting in invalid code. This issue has been fixed in #21018
