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

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"`.
