No syntax highlighting of expressions inside title tag

[diontron]

First off, thank you so much for this plugin.

I am not getting syntax highlighting / completion inside svelte:head eg:

<script>
    export let app
</script>

<svelte:head>
    <title>Hello | {app.name}</title>
</svelte:head>

<h1 class="text-3xl font-bold underline">
    Hello world! {app.name}
</h1>

I get it inside the h1, but not inside svelte:head.
