md-input-container placeholders can disappear behind input

[hans-pragt]

Bug, feature request, or proposal:

If the value of an <input> element is set through data binding, tabbing into and out of will cause the placeholder to act as if there is no input and lower itself behind the input text.

What is the expected behavior?

The placeholder works correctly regards of how the value of the input it set.

What is the current behavior?

The placeholder sits behind the text in the input.

What are the steps to reproduce?

You will see the wrong behavior here:

After editing the text in the input, the placeholder will stay in the right spot.

Which versions of Angular, Material, OS, browsers are affected?

Windows 10 / Chrome 55.0.2883.87 m

Is there anything else we should know?

I like the new plunkr template, thanks for updating it.
