md-input-containers text and floating label misaligned when using mdPrefix #3229

When using a md-icon as a prefix to an input inside of an md-input-container the floating label gets misaligned when using a mdPrefix, as you can see below:

The expected behavior is to have the text aligned with the icon and also have the floating label be at the correct position. As you can see when there is no mdPrefix icon the text is all aligned how it should be:

To reproduce this simply add a mdPrefix to a md-input-container.
Before:

<md-input-container>
    <input mdInput placeholder="text" type="text" name="example">
</md-input-container>

and after:

<md-input-container>
    <md-icon mdPrefix>email</md-icon>
    <input mdInput placeholder="text" type="text" name="example">
</md-input-container>

Right now using mdPrefix is making the input not look good. If I am using mdPrefix wrong please let me know.
