MdInput - Placeholder does not float when using formControl setValue()

Bug

What is the expected behavior?

Placeholder should be floating over input when setting the input value using setValue of its formControl.

What is the current behavior?

When I use setValue, the input contains the value set and the placeholder overlays the value, without floating over it. If I enter a text manually just after using setValue, the placeholder goes to the right place.

What are the steps to reproduce?

Here's a plunker that reproduces the issue:

In the meantime, if you are only experiencing this because the initial setting of the values is async then you could provide "dummy values" to the form controls when you create them, so that the input directive thinks that they are not empty before the setValue finally fills them.
