[css-lists] List items without ul/ol and quirks?

[kojiishi]

Recently bug 811172 was filed to Chrome about this.

I learned that in this case:

Browsers	Behavior
Gecko (quirks), Edge (quirks), WebKit, Blink	The list markers appear as if inside.
Gecko, Edge	The list markers honor the list-style-position property.

I haven't found if this case was defined, but two questions:

1. Do we want to match to Gecko/Edge behavior?
2. Do we want to keep the quirks behavior?

Our (quirks) behavior is intentional. I don't recall seeing an issue about it. I guess if an issue has been filed against you to match us, it's reasonable to match us in this scenario.

Our (quirks) behavior is also documented here:
https://msdn.microsoft.com/en-us/library/gg558047(v=vs.85).aspx

List item markers. The default value of list-style-position is "inside" if the list-item is outside a <UL> or <OL> element, and "outside" otherwise.

Also, I think the behavior in Chrome will need to be updated anyway because you can't even force "outside" on such a list item with a "list-style-position: outside !important" rule :-(

I'm fairly sure that this is a violation of the spec.

I personally think keep it outside is better.

1. Outside is the default value, and the computed style displayed by inspector is also outside. Changing to inside, make it confusing.
2. The cost is smaller to make an outside single LI inside than the contrary.
