Loving it so far!
Is there any way to enforce elements’ status as Vaadin does with components?
e.g. you can remove ‘v-disabled’ for a button, but clicking it won’t trigger an event; however, doing the same with ‘disabled’ for a paper-button will.
There’s unfortunately no easy way of keeping the visual representation and the server-side disabled state in sync. I’ve created https://github.com/vaadin/serverside-elements/issues/13 about this.
