inheriting attributes on <Show> fallback & children

[Upbolt]

for instance

use leptos::{prelude::*, html::div};

#[component]
pub fn Foo(children: ChildrenFn) -> impl IntoView {
  let as_child = RwSignal::new(false);

  let children = StoredValue::new(children);
  let children = move || children.with_value(|children| children());

  view! {
    <Show
      when=move || as_child.get()
      fallback=move || div().child(children())
    >
      {children()}
    </Show>
    <button on:click=move |_| as_child.update(|as_child| *as_child = !*as_child)>swap</button>
  }
}

and when used like so

#[component]
fn App() -> impl IntoView {
  view! {
    <Foo attr:data-foo="test">
      <span>test</span>
    </Foo>
  }
}

should (or at least what i expected) yield

<span data-foo="test">test</span>

or

<div data-foo="test">
  <span>test</span>
</div>

could be unintended behavior or something that i'm missing, but regardless no attributes specified in the component's usage is emitted

big thanks in advance ️‍🔥

looking back on a previous discussion (#2922 (reply in thread)) it looks like <Show> would need to be changed to require more type information from its fallback

well that's embarrassing, turns out i overthought it; this is solved with a simple match + Either
