Hi there 😄

After upgrading from v1.1.4 to v1.3.2, I noticed that my attributes were no longer shadowed by initializeAttrs(). I started digging and stumbled upon this piece of logic introduced in #191:

It prevents initializeAttrs() from doing anything the second time around, thus skipping the manual initialization of attributes. Also, it seems like this change was one of the main things addressed by the above-mentioned PR.

So, what would be the correct way now to initialize the attributes without the @attr decorator?

Thanks!

Example

<script>
  class InfoMessage extends HTMLElement {
    open = true

    connectedCallback() {
      initializeAttrs(this, ['open'])
    }
  }

  controller(InfoMessage)
</script>

<info-message data-open="false"></info-message>

1. controller(InfoMessage) wraps original connectedCallback() and calls:

2. InfoMessage is marked as initialized (attrs.ts):

3. The original connectedCallback() is executed, but initializeAttrs() would hit that early-return condition.
4. this.open is stuck in its default state (true) 😔
