SIA-R83 should accept single words in scripts that allow hyphenation

[Jym77]

We've seen a few false positives on <div> or <li> that contain a single word. The element's bounding box is the full line, so Alfa doesn't see that the text is actually short and doesn't need wrapping, and since the text is a single word Alfa doesn't find a soft wrap opportunity and flags it incorrectly.

<ul style="overflow: hidden">
  <li>Hello</li>
</ul>
