prettier not formatting things correctly

[jaxramus]

I am using https://github.com/prettier/prettier with the default settings

For example, let's say I have this:

render() {
    return html`<div><h1>Hello</h1><p>I love coding.</p></div>`
}

Prettier correctly formats it to this:

render() {
    return html`<div>
        <h1>Hello</h1>
        <p>I love coding.</p>
    </div>`;
}

Now let's say I have this:

render() {
    return /*html*/`<div><h1>Hello</h1><p>I love coding.</p></div>`
}

Prettier does not format it whatsoever. Notice how instead of html I am using /*html*/ because I am not using lit-html, but I still want to have syntax highlighting and formatting for html string literals.

How can I get prettier to format it correctly?
