Hey there maintainers :)

First of all, thank you very much for this library! It has really made the difference for me and my company on how focused and reliable it is, specially compared to other "tooltip/popovers" libraries.

Hello,

Using vanilla JS, I noticed that "onUpdate" is being called on any event on the page, not only when the results list is updated, as the documentation states.

Here's a Codepen example forked from "Simple autocomplete - @trevoreyre/autocomplete-js"

Even if clicking around the page, no relation to the autocomplete, the "onUpdate" is called.

The component currently uses a plain <vaadin-text-field> internally, which can be problematic when it comes to theming. Create and change the template to use an extension (<vaadin-combo-box-text-field>) instead.
