Describe the bug

Not sure if this is expected behavior, but I found that inside the <svelte:head> tag, intelisense just not working when typing or hit Ctrl + Space.

Reproduction

<svelte:head>
<style>
    .test-class {
        color: red;
    }
</style>
</svelte:head>

Cannot hover on value to see infomation.
Cannot Ctrl+Space to see the right suggestions.
etc...

Expected behaviour

Intellisense should work normally.
