This class is...

(Nit: You could consider putting CompositionUnderlineBuilder and
CompositionUnderlineVectorBuilder in the same file.)

Done.

TBH I'm from the one class -> one file school - is there any general guidance in
blink?

[haraken, 2017/04/21 06:18:54]

I don't know. We normally create one file per class but put closely-related
classes into the same file.

 // to Vector<CompositionUnderline>.
 
-class CompositionUnderlineVectorBuilder : public Vector<CompositionUnderline> {
+class CORE_EXPORT CompositionUnderlineVectorBuilder
+    : public Vector<CompositionUnderline> {
  public:
   CompositionUnderlineVectorBuilder(const WebVector<WebCompositionUnderline>&);
 };
 
 }  // namespace blink
