summary element styling needs to be scoped to details element

[scottaohara]

The current display style applied to the summary element results in unwanted list-item styling for instances where the summary element is not used properly.

summary {
  display: list-item;
}

This should rather be something like details > summary:first-of-type - which matches how modern browsers are treating the element.

Hey, is this issue open?
