Generic type parameters disappear

[tversteeg]

When I copy this example:

#[component]
fn SizeOf<T: Sized>(#[prop(optional)] _ty: PhantomData<T>) -> impl IntoView {
    std::mem::size_of::<T>()
}

#[component]
pub fn App() -> impl IntoView {
    view! {
        <SizeOf<usize>/>
        <SizeOf<String>/>
    }
}

And format it, the <usize> and <String> type parameters disappear:

// ...

#[component]
pub fn App() -> impl IntoView {
    view! {
        <SizeOf/>
        <SizeOf/>
    }
}
