Ah, thanks for clarifying that, everyone.

According to the css-conditional-5,  it describes about figuring out the container from the ancestor.
> For each element, the query container to be queried is selected from among the **element’s ancestor query containers that are established as a valid query container** for all the container features in the . If the contains unknown or unsupported container features, no query container will be selected for that . The filters the set of query containers considered to just those with a matching query container name.

I initially thought this api is likely `matchSelfAsContainer`. Maybe it is good to mention this on the spec. 

FWIW, If we need like  `matchSelfAsContainer` maybe, we can remove the word container from the API.
