Attribute not removed in the DOM ( probably when setting the control back to default value )

[herrKlein]

Hi,

again, thanks for this helper library. It saves so much time documenting all our components.

I have a reproducible 'bug' when setting a control back to its original state.

I added a shuffle property to the element in your stackblitz example

https://stackblitz.com/edit/github-zzm7be2d?file=README.md,src%2Fmy-element.ts

  @property({ type: String, reflect: true })
  shuffle: 'true' | 'false' = 'false';

There now is a control in storybook, the select.
When I set shuffle to true, the shuffle attribute shuffle="true" is shown inside the code block, and in the dom.

But when setting it back to false in the controls, in the code block the attribute disappears from the element. ( this appears to be correct, it is the default value ) .. but the attribute is not removed in the real dom element, shown in chrome devtools. it still is shuffle="true" in the DOM.

it should be removed in the DOM also.

Let me take a look.

Any luck finding the problem of this issue?
