[BUG] formatter removes block comments

[NishantJoshi00]

rustfmt removing block comments that are present in between field name and field type. (observed for a struct).

System Details

• rustc: rustc 1.81.0 (eeb90cda1 2024-09-04)
• cargo: cargo 1.81.0 (2dbb1af80 2024-08-20)
• rustfmt: rustfmt 1.7.1-stable (eeb90cda 2024-09-04)

Reproducible Example

pub struct Account {
    id: uuid::Uuid,
    account_number: String,
    holder_name: String,
    holder_ref: /* Box<super::holder::Holder> */ uuid::Uuid,
}

Let's say I have the struct that looks something like this. Now when I run cargo fmt on this, the code is transformed into:

pub struct Account {
    id: uuid::Uuid,
    account_number: String,
    holder_name: String,
    holder_ref: uuid::Uuid,
}

The formatter removes the block comment completely.

I am not super familiar with this codebase, I'll try to look around and figure out what changes might be needed for this. But it would be great if something can help me out with this.
