External meta <Script/>: could not convert current node into marker node

Describe the bug Scripts seem to be able to break leptos hydration, when used inside a <Scripts /> tag, errors with the marker node. This repro uses a google analytics script, this just happened to be how I could repro it.

Leptos Dependencies Current main.

To Reproduce

#[component]
pub fn App() -> impl IntoView {
    provide_meta_context();

    view! {
        <Script src="https://www.googletagmanager.com/gtag/js?id=abcdefg" />
        <main>
            <Router>
                <Routes fallback={|| {
                    view! { <p>Foo</p> }
                }}>
                    <Route path={path!("/")} view={|| view! { <p>Bar</p> }} />
                </Routes>
            </Router>
        </main>
    }
}

I've verified this happens in a fresh project, checked in counter_isomorphic, where I had to add leptos_meta then replace the Counters component with this App and add <MetaTags /> to the shell in main.rs.

I have no idea if it's related or separate, but I'm having another similar issue after setting up a blocking resource. I'll add the basics in case it's useful, but don't have a good repro, hopefully fixed by the main repro of this issue above!

I have a simple anchor tag inside a site navbar (this is in an Either::Right(view!{...}) of a reactive block of whether a user is logged in or not, the user being logged in is a blocking resource):

view! {
    <a href="/login">"Login"</a>
}

The direct error is:

ERROR: 
      /Users/zak/z/code/leptos/tachys/src/html/element/mod.rs:353:14
      Panic: called `Option::unwrap()` on a `None` value

Looking at the source, I added a print above this line for cursor.current() to see what it was failing on, it prints "Login", whereas everything else prints an html element, so I think this is why it errors on element extraction here, and how I pinpointed this anchor.

Interestingly, if I change the view to:

view! {
    <div>
        <a href="/login">"Login"</a>
    </div>
}

The error then changes to:

ERROR: 
      /Users/zak/z/code/leptos/tachys/src/hydration.rs:99:14
      Panic: could not convert current node into marker node

If remove the view entirely, so in this case it becomes Either::Right(()) the error goes back to original, but the debug print now prints out "", so there's clearly some mismatch in the dom.

ERROR: 
      /Users/zak/z/code/leptos/tachys/src/html/element/mod.rs:353:14
      Panic: called `Option::unwrap()` on a `None` value

If this doesn't get solved once this direct repro is and this issue is shut, I'll open a separate issue afterwards, just adding in case it helps.
