Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
This text should be autosized to 40px computed font-size, since it's only 50px narrower than the previous child and therefore remains the part of the same cluster.
This text is not autosized since it's too narrow and is considered to be a separate autosizing cluster.
