What Hacker News says
4 sourcesRandom aside. Their code snippet has this comment:
// popovers have light dismiss which influences our state
And I hadn't heard of that phrase before! Turns out it means "clicking elsewhere closes the thing:"
> "Light dismiss" means that clicking outside of a popover whose `popover` attribute is in the auto state will close the popover.[0]
Like what, say, a `<select>` does when open.
Strikes this dev as a pretty unintuitive way to phrase that. At first I thought it was "light" as in "light DOM," but I guess it's "light" as an antonym of "explicit?" Looks like there was some back and forth on this, and it was even proposed as an attribute: https://github.com/openui/open-ui/issues/834

In Introducing command And commandfor In HTMLThe aim of <selectedoption> is to provide a DOM placeholder to contain a clone of the contents of the selected <option>. It isn't there as a style hook for the selected option in the popover - that already exists via option:selected.
You aren't the first to get mixed up here. Personally I think <selectedoption> is a misleading name. I wish it was called something like <selectedcontent>, but I don't know if that is much better https://github.com/openui/open-ui/issues/1112
