[css-houdini-drafts] [css-typed-om] Clarify list-valued properties

andruud has just created a new issue for https://github.com/w3c/css-houdini-drafts:

== [css-typed-om] Clarify list-valued properties ==
If a property optionally takes a non-list as a value, is it a [list-valued property](https://drafts.css-houdini.org/css-typed-om-1/#list-valued-properties)?

Examples:

1. `counter-reset`
2. `transform`
3. `content`
4. Custom property with syntax `none | <length>+`

If such properties are list-valued properties, what should happen when you do e.g. `e.attributeStyleMap.append('counter-reset', 'none')`?
