Description Ryosuke Niwa 2018-08-14 00:08:57 PDT
Apparently, I unintentionally disabled foster parenting for synchronously defined custom elements.

On one hand, this doesn't match the spec. On the other hand, being able to define custom elements anywhere seems useful
especially given there doesn't seem to be any compact issues (given WebKit has been shipping this behavior for two years).
