svelte:head does not remove title tag

[mallsoft]

Describe the bug

A title tag added using <svelte:head>, cannot be removed? like you can with any other tag i have tested (meta, script).

Reproduction

<svelte:head>
	{#if toggleBool}
	<!-- stays put even if toggleBool is false  -->
		<title>Title injected!!!</title>

	<!-- gets removed as expected  -->
		<meta name="description" content="I am ALIVE" />

	<!-- gets removed as expected  -->
		<script>
			console.log('I am alive!');
		</script>
	{/if}
</svelte:head>

I think thats on purpose, because when you would remove the title, without setting a new one the page would have no title at all. So the only way to change the title is to set a new one.
You could of cause keep track of the previeous titles and set it to the last one. This could be a possible solution

This actually blocks fallback titles, maybe we can (at least) remove the title when one is present in a parent, like:

<!-- src/routes/+layout.svelte -->
<svelte:head>
  <title>Fallback</title>
</svelte:head>

<!-- src/routes/+page.svelte -->
<svelte:head>
  <title>Home</title>
</svelte:head>

<a href="/404">Go to 404 page</a>

Give the above example a direct call to "/404" will result in the title "Fallback" while a call using CSR will result in the old title "Home" still being displayed instead of the fallback one.
