Summary [CSS Regions] getRegionsByContent() false positive for overset content

Load page into browser. The page runs a timer to successively hide green content elements. At each step, the message reports on getRegionsByContent() matches for red content. Before trailing red content comes into view, getRegionsByContent() inaccurately reports that the last region in the chain contains part of it. The # of regions should be 0 until red content becomes visible. I assume this behavior would be valid if region-fragment (or -webkit-region-overflow) were not set to 'break', i.e., when overflow-y makes downstream red content accessible.
