Created attachment 215932 [details] Test case. The attached test case demonstrates that the problem is due to specifying a non-zero margin (not shape-margin) for the shape-outside element.

Created attachment 215940 [details] Patch When margin-top is specified for a shape's element, the Y coordinates passed to RasterShapeIntervals::getExcludedIntervals() may be negative. This is because the incoming logical coordinates are relative to the content or padding box, depending on the box-sizing property. The RasterShape::getExcludedIntervals() method now clips the incoming Y coordinates to the shape's bounds.
