Actually there are bunch of existing 'input' event tests (and I got some hard
time fixing them), so I only updated this single one :)

         lastInputType = event.inputType;
     });
     if (!window.eventSender) {
         document.write('This test requires eventSender');
     } else {
-        var kNoBeforeInputFired = 'noBeforeInputFired';
+        var kNoInputEventFired = 'noInputEventFired';
         function testKeyDownInputType(key, modifiers, inputType) {
-            lastInputType = kNoBeforeInputFired;
+            lastBeforeInputType = kNoInputEventFired;
+            lastInputType = kNoInputEventFired;
             eventSender.keyDown(key, modifiers);
+            assert_equals(lastBeforeInputType, inputType, `${modifiers.toString()}+${key} should produce beforeInputType: ${inputType}`);
             assert_equals(lastInputType, inputType, `${modifiers.toString()}+${key} should produce inputType: ${inputType}`);
         }
