rustdoc fails to display const generics correctly

[DutchGhost]

Having the following code in lib.rs:

#![feature(const_generics)]

use core::ops::Add;

pub struct Simd<T, const WIDTH: usize> {
    inner: T
}

impl Add for Simd<u8, 16> {
    type Output = Self;

    fn add(self, rhs: Self) -> Self::Output {
        Self { inner: 0 }
    }
}

produces a funny looking rustdoc page:

Maybe related to #60737 ?
