Ting-Yu might recall something about details/summary :)

[Emilio Cobos Álvarez (:emilio)]

Probably <summary> should do something like what <label> does?

Attachment: Bug 1524893 - Override IsInteractiveHTMLContent() for HTMLDetailsElement.

When nsGenericHTMLElement::IsInteractiveHTMLContent() was introduced,
HTMLDetailsElement didn't exist yet. It's better to override
IsInteractiveHTMLContent() for HTMLDetailsElement than check the details
tag in its parent class.

Depends on D18791
