Created attachment 174825 [details] Screenshot, Console (Chromium) Copy HTML into local file & load. Resize page so that content overflows final purple region in the region chain, with boundary between last & second-to-last paragraphs displaying within region. (2nd-to-last ends "livvy"; last starts "What clashes"; see attached screen shot for example.) These two paragraphs are interrupted by another <aside> content element that's diverted to a different named flow. Reload page. Console lists final region's getRegionFlowRanges() as content strings. Expected behavior: text should appear for 2 ranges, the second starting "What clashes" Actual behavior: as shown in attached screen shot, only the first range has text. There is a second range, apparently empty.
