Description Ryosuke Niwa 2018-08-15 20:54:11 PDT
Via step 6.2. of https://dom.spec.whatwg.org/#concept-create-element
to step 13.2. of https://heycam.github.io/webidl/#construct-a-callback-function
to step 3 of https://html.spec.whatwg.org/multipage/webappapis.html#clean-up-after-running-script
we should be executing microtasks immediately after constructing a custom element.

This bug was caught by a test case in LayoutTests/imported/w3c/web-platform-tests/custom-elements/microtasks-and-constructors.html
