Re: [whatwg/dom] Make it possible to observe connected-ness of a node via MutationObserver (#533)

@caridy, I'm not sure if I believe a synchronous approach will be able to move forward since we had that with Mutation Events (which as you say doesn't work reliably with Shadow roots) and one of the primary reasons to move away from them in favor of MutationObserver was their synchronous nature. I'm certain you have perfectly valid reasons to want a synchronous solution, and I agree that this is an important missing piece in the web platform right now, but if we can find a way to move forward with an asynchronous approach and with an API that is similar to other related observers such as MutationObserver, I think the odds of getting implementors behind this is greater. I've experimented with this and created a library called [ConnectionObserver](https://github.com/wessberg/connection-observer) which batches connection entries together in microtasks, and I'd like to propose something similar to that.
