16 This text should be autosized to

21 This text should be autosized to
30px computed font-size (
16 *
600/
320), since its width:
600px makes it wider than the lowest common ancestor of its enclosing cluster, hence it will itself become a cluster.

26 This text should be autosized to
20px computed font-size (
16 *
400 /
320), since it's not an autosizing cluster itself and its parent element is the enclosing autosizing cluster which is
400px wide.
