start yew app as body element without clearing header

[beckend]

Using yew in a bundler, you would have yew built with wasm-pack.
The bundler has an entry point where it loads the wasm, along with injected css bundles/hot reloaders inside the header.

It seems like there is no method which omits clearing the html element completely

yew/packages/yew/src/app_handle.rs

Line 26 in 09a41d6

clear_element(&element);

Trying to do it manually by creating a new scope is not possible either, since scope::new is private

yew/packages/yew/src/app_handle.rs

Line 28 in 09a41d6

scope: Scope::new(None),
