You're constructing a new textrun here. Why doesn't the textrun from above (line
806) work?

+            TextPainter::Style textStyle = TextPainter::textPaintingStyle(m_inlineTextBox.layoutObject(), style, true, false);
+            LayoutRect boxRect(boxOrigin, LayoutSize(m_inlineTextBox.logicalWidth(), m_inlineTextBox.logicalHeight()));
+            LayoutPoint textOrigin(boxOrigin.x(), boxOrigin.y() + font.fontMetrics().ascent());
+            TextPainter textPainter(pt, font, textRun, textOrigin, boxRect, m_inlineTextBox.isHorizontal());
+
+            textPainter.paint(sPos, ePos, length, textStyle, 0);
+        }
     }
 }
