Bug - regression

**What is the current behavior?**

In react 16 when creating a `<select size="3">` (size > 1) the first child <option> is automatically getting marked as selected. In React 16 there does not seem to be a way to specify no <option> gets selected by default

**What is the expected behavior?**

In React 15 unless you marked an option to be selected <option selected> no options were selected by default.

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

Reproducible in Chrome 72 and Firefox 59.

**Note:** this is almost a duplicate of #12200. In fact, I copied issue text and codesandbox examples, just changing `multiple` to `size="3"`.
<option value="monkey">A monkey!</option>
          <option value="giraffe">A giraffe!</option>
        </select>,
      );
      expect(node.value).toBe('');
    });
    it('treats updated function defaultValue as an empty string', () => {
      let node;
      expect(() => {
        node = ReactTestUtils.renderIntoDocument(
          <select defaultValue="monkey">
            <option value={() => {}}>A function!</option>
            <option value="monkey">A monkey!</option>
            <option value="giraffe">A giraffe!</option>
          </select>,
        );
      }).toWarnDev('Invalid value for prop `value`');
      expect(node.value).toBe('monkey');
      node = ReactTestUtils.renderIntoDocument(
        <select defaultValue={() => {}}>
          <option value={() => {}}>A function!</option>
          <option value="monkey">A monkey!</option>
          <option value="giraffe">A giraffe!</option>
        </select>,
      );
      expect(node.value).toBe('');
    });
  });
});
