Accessibility implements the "Forming a table" algorithm for computing its cell slots: https://html.spec.whatwg.org/multipage/tables.html#forming-a-table In this model, rowspan="0" is a special value that states the cell should span all remaining rows. Prior to recent change https://bugs.webkit.org/show_bug.cgi?id=185341, the visual rendering for rowspan="0" was not correct — it equated the zero value to rowspan=1. So we did the same in the accessibility implementation, ensuring we match what is visually rendered. But with the change from bug 185341, the visual rendering now spans all remaining rows as is specified. We need to update the accessibility implementation of the algorithm to match.
