That seems like a very wrong way to use MutationObservers. @rniwa's approach is the correct one; I'm not sure where you got the idea that they "leak memory" or are "kept proper" by for some reason tying them to connectedCallback and disconnectedCallback. Mutations can happen any time; connected or not.
