<!-- Please provide a detailed description of the issue. Include specific details to help us understand the problem. -->

__Description:__
When the `value` attribute is bound in a `<textarea>` tag, and the binding returns `undefined` via a getter, undefined renders in the textarea as though the user had typed it. This does not happen if `null` is returned by the getter, nor does it happen if you set the `default` value to `undefined`


<!-- List the step-by-step process to reproduce the issue. -->

__Steps to reproduce:__
see this codepen for an easy example:

<!-- Describe what you expected to have happen after completing the steps above. -->

__Expected results:__
I would expect a returned value of `undefined` would not render anything, just like `null`
