`<style>` tag support in JSX

[thescientist13]

Summary

Currently there does not seem to be a way to do <style> tags in JSX content.

export default class Header extends HTMLElement {

  connectedCallback() {
    this.render();
  }

  render() {
    return (
      <div>
        <style>
          :host p {
            text-align: 'center';
          }
        </style>
        <header>
          <p>Welcome to my site</p>
        </header>
      </div>
    );
  }
}

customElements.define('app-header', Header);

You can also the IDE complaining as well

Details

Something like this will work though

const styles = `
  :host p {
    text-align: 'center';
  }
`

export default class Header extends HTMLElement {

  connectedCallback() {
    this.render();
  }

  render() {
    return (
      <div>
        <style>
          {styles}
        <header>
          <p>Welcome to my site</p>
        </header>
      </div>
    );
  }
}

customElements.define('app-header', Header);

Seems like this is the state of things and not sure there's any good solution around it, so not sure what our options are here though, if any?
