Describe the Bug

Astro.slots.render lets you optionally pass an array of arguments:

const html = (await Astro.slots.render("title", [prefix]));

If the slot has a "function child", the elements of this array will be passed to that function. In the "default" slot case, it works as expected. You'd pass a function like this:

<GimmeDefaultFunctionSlot>{(foo, bar) => (<div>{foo} {bar}</div>)}</GimmeDefaultFunctionSlot>

But in the named slot case, the contents of the slot get rendered, but the slot element itself disappears.

<GimmeFunctionSlot>
	<h1 slot="title">
		{(prefix) => <span>{prefix + "Fuzzy"}</span>}
	</h1>
</GimmeFunctionSlot>

This will render the span, but not the h1.
