trait Tr {}
type Huh<T> where T: Tr = isize;
fn main() {}

results in:

Seems to be the same as #22471, the internal error isn't exposed anymore, test added in #24979. The code example given here is now failing with

test.rs:2:27: 2:32 error: type parameter `T` is unused [E0091]
test.rs:2 type Huh<T> where T: Tr = isize;

fix: Fix TokenStream::to_string implementation dropping quotation marks

Fixes rust-lang/rust-analyzer#17986
We might wanna consider backporting this to beta if that's simple enough to do
