Element stops working if taken off the DOM and put back in

[Baptouuuu]

An element javascript seems to stop working when you take the element off the document DOM and then afterward put the element back in. I came across this problem with the element core-input and paper-toast.

For the first one, the event change is no longer firing. And the latter one doesn't show up when calling the method show.

There ist cancelUnbindAll(preventCascade: true); in Dart I guess there is something similar in JS

Thanks. Found the preventDispose attribute.
