**Do you want to request a *feature* or report a *bug*?**

bug? Maybe.

**What is the current behavior?**

Using non-delegated handler for submit event.

**What is the expected behavior?**

After IE9, at least I know, submit event bubbled up.

**Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?**

16.2.0
expect(document.activeElement.id).toBe('one');
        input2.focus();
        expect(document.activeElement.id).toBe('two');
        log.push('input2 focused');
      }
    }
    const log = [];
    const container = document.createElement('div');
    document.body.appendChild(container);
    try {
      ReactDOM.render(<A showTwo={false} />, container);
      input.focus();
      
      
      
      
      const div = container.firstChild;
      ['appendChild', 'insertBefore'].forEach(name => {
        const mutator = div[name];
        div[name] = function() {
          if (input) {
            input.blur();
            expect(document.activeElement.tagName).toBe('BODY');
            log.push('input2 inserted');
          }
          return mutator.apply(this, arguments);
        };
      });
