There's nothing said in https://drafts.csswg.org/css-scoping/#host-selector about whether :host is the only thing allowed in a compound selector.

However the following shows red in both Blink and WebKit, when I expected it to show green:

<!doctype html>
<div id="host"><span>In host</span></div>
<script>
  let root = host.attachShadow({ mode: "open" });
  root.innerHTML = `
    <style>:host { background: red }</style>
    <style>#host:host { background: green }</style>
    <span>In root</span>
  `;
</script>

Should this be specified better? Am I misreading the spec or missing something? I'm looking into implementing this in Firefox and I really didn't expect to have to just copy whatever WebKit and Blink are doing.

@lilles pointed out in #2423 the section of the spec I was missing.
