[Webkit-unassigned] [Bug 184307] CustomElements are not always properly upgraded when created via innerHTML

--- Comment #2 from Frédéric Wang (:fredw) <fred.wang at free.fr> ---
Setting innerHTML ends up calling replaceChildrenWithFragment (from Source/WebCore/editing/markup.cpp) which performs several node operations internally (e.g. appendChild). These operations have CEReactions and so should ensure upgrade reactions are invoked when using the public DOM API: https://dom.spec.whatwg.org/#interface-node ; I wonder if we should do something similar winternally.
