I feel this is an expected behaviour.

See: https://docs.rs/yew/latest/yew/macro.html_nested.html

This macro is similar to html!, but preserves the component type instead of wrapping it in Html.

The documentation suggested that only <Comp /> is preserved as VChild<Comp>.

Returning other types would encourage inspection of VNode, which I am not in favour of.
