Expectations for presentational element with title child?

Hey all.

I'm doing the golden-hammer-ectomy for WebKit at the moment. I would
like the task force's expectations for one of my/WebKit's test cases,
please and thank you. :)

<svg>
  <g id="test" role="presentation">
    <title>Venn Diagram</title>
    <circle cx="50" cy="50" r="20" aria-label="set A"/>
    <circle cx="50" cy="75" r="20" aria-label="set B"/>
  </g>
</svg>

Should the "g" element with id of "test" be:
a. Excluded from the tree because of the presentational role
b. Included in the tree because of the "title" element
c. To be discussed further before consensus can be reached

Thanks!
