Best place for inView?

[bakura10]

Hi :),

In the context of a custom element, would it be better to have the inView being registered in the constructor or the connectedCallback? As connectedCallback can be called more than once, I think it makes it a not so good candidate, but I wonder if there is any potential drawback of having this being registered in the constructor, at a stage where the element may not be in the DOM yet?

Thanks :)
