It might be worth putting a comment here explaining why they're named Tb / Rl /
Lr :)

 
 // Lines have horizontal orientation; modes horizontal-tb.
 inline bool isHorizontalWritingMode(WritingMode writingMode) {
-  return writingMode == TopToBottomWritingMode;
+  return writingMode == WritingMode::HorizontalTb;
 }
 
 // Bottom of the line occurs earlier in the block; modes vertical-lr.
 inline bool isFlippedLinesWritingMode(WritingMode writingMode) {
-  return writingMode == LeftToRightWritingMode;
+  return writingMode == WritingMode::VerticalLr;
 }
 
 // Block progression increases in the opposite direction to normal; modes
 // vertical-rl.
 inline bool isFlippedBlocksWritingMode(WritingMode writingMode) {
-  return writingMode == RightToLeftWritingMode;
+  return writingMode == WritingMode::VerticalRl;
 }
 
 }  // namespace blink
