Property-less lit-elements are not rendered about lit-element HOT 3 CLOSED

Hmm, I can't repro this. Here's a glitch (code, demo) where I'm just rendering the following element, and it shows up fine:

class AThing extends LitElement {
  static get is() {
    return 'a-thing';
  }
  render() {
    return html`
      hi! this is a thing.
    `;
  }
}
window.customElements.define(AThing.is, AThing);

Based your initial issue title, I also included in the demo rendering two nested, no-properties elements, and that works fine too.

Thanks for the response and time taken to triage, @notwaldorf. I will reopen this if I can reproduce this in a glitch.

In my project, I had an empty properties object returned like this:

static get properties() {
  return {};
}

which caused a no render. Filling it with at least a property helped. Couldn't immediately reproduce this in a Glitch, I will play with it again and see.

I think that if you just return {}, you don't really need to add that properties block :)
