This simplifies the state machine which controls whether I should start doing actions (animation, retrieving stuff, event listening, etc.) and stop doing actions. Olli: It seems unfortunate to for custom element authors to use MutationObservers for this. All created custom elements will need to register mutation observers over the entire document to see whether one of their elements is inserted anywhere. It seems much more efficient for implementations and simpler for authors if the UA provides these callbacks. I *think* it is fine for the callbacks to be timed to the microtask like a MutationObserver to avoid the pathologies of MutationEvents. -- You are receiving this mail because: You are the QA Contact for the bug.
