-/// Test for the Selectors API ported from
-/// <https://github.com/w3c/web-platform-tests/tree/master/selectors-api>
-///
-/// Note: tried to make minimal changes possible here. Hence some oddities such
-/// as [test] arguments having a different order, long lines, etc.
-///
-/// As usual with ports: being faithful to the original style is more important
-/// than other style goals, as it reduces friction to integrating changes
-/// from upstream.
