See https://lists.w3.org/Archives/Public/public-webapps/2015JanMar/0731.html

We should make the custom element's constructor be called synchrnously instead of at the end of the micro-task since that's not consistent with builtin elements and exposes "unconstructed" elements in some cases; e.g. immediately after cloning or setting innerHTML.
