Could you add short description of this interface to follow [1]?

2. Classes should have a class-level comment.

ctor should have protected accessibility. Since we can't instantiate this class.

+
+  virtual ~DocumentMarkerList();
+
+  virtual bool IsEmpty() const = 0;
+
+  virtual void Add(DocumentMarker*) = 0;
+  virtual void Clear() = 0;
+
+  virtual const HeapVector<Member<RenderedDocumentMarker>>& GetMarkers()
+      const = 0;
+
+  // Returns true if at least one marker is copied, false otherwise
+  virtual bool MoveMarkers(int length, DocumentMarkerList* dst_list) = 0;
+
+  // Returns true if at least one marker is removed, false otherwise
+  virtual bool RemoveMarkers(unsigned start_offset, int length) = 0;
+
+  // Returns true if a marker was removed, false otherwise.
+  // TODO(rlanday): remove this method from this interface once we have a
+  // Spelling/Grammar-specific marker list impl to put this on
+  virtual bool RemoveMarkersUnderWords(const String& node_text,
+                                       const Vector<String>& words) = 0;
+
+  // Returns true if at least one marker is shifted or removed, false otherwise
+  virtual bool ShiftMarkers(unsigned offset,
+                            unsigned old_length,

+  DISALLOW_COPY_AND_ASSIGN(DocumentMarkerList);

DISALLOW_COPY_AND_ASSIGN(...) should have private accessibility.

It seems PRESUBMIT doesn't check this for Blink directory.
