similar to InlineFlowBox InlineFlowBox::placeBoxesInBlockDirection const FontMetrics& fontMetrics = lineStyle().fontMetrics(); // RootInlineBoxes are always placed on at pixel boundaries in their logical y direction. Not doing // so results in incorrect rendering of text decorations, most notably underlines. setLogicalTop(roundToInt(top + maxAscent - fontMetrics.ascent(baselineType))); missing roundings are in: RunResolver::Run::baseline() RunResolver::Run::rect()
