Maybe not needed?

The fwd reference class HTMLSourceElement @12 right, to be precise.  Looked over
the rest of the patch in more detail, seems fine.

LGTM and thanks for the compat info in ChangeLog.  Mike will need to look also.

 class HTMLPictureElement final : public HTMLElement {
     DEFINE_WRAPPERTYPEINFO();
 public:
     DECLARE_NODE_FACTORY(HTMLPictureElement);
 
-    void sourceOrMediaChanged();
+    void sourceOrMediaChanged(HTMLElement*, Node* next = nullptr);
 
 protected:
     explicit HTMLPictureElement(Document&);
 
 private:
     InsertionNotificationRequest insertedInto(ContainerNode*) override;
 };
 
 } // namespace blink
 
 #endif // HTMLPictureElement_h
