I was going to put NotHandled at the end of this list. But it made the
mergeEventResult code less simple.

+    // Event was consumed but suppressed before dispatched to application.
+    HandledSuppressed,
+    // Event was consumed by application itself; ie. a script handler calling preventDefault.
+    HandledApplication,
+    // Event was consumed by the system; ie. executing the default action.
+    HandledSystem,
+};
+
+} // namespace blink
+
+#endif // WebInputEventResult_h
