Incorrect rustdoc rendering of const generic default

[bjorn3]

I tried this code:

https://doc.rust-lang.org/nightly/std/mem/trait.TransmuteFrom.html

pub unsafe trait TransmuteFrom<Src, const ASSUME: Assume = { Assume::NOTHING }> where Src: ?Sized {}

I expected to see this happen: Renders identically to the above in the rustdoc output.

Instead, this happened: Renders as

pub unsafe trait TransmuteFrom<Src, const ASSUME: Assume = core::::mem::transmutability::TransmuteFrom::{constant#0}> where Src: ?Sized {}
