md-stretch-tabs="always" not working

[jasonke]

This codepen example http://codepen.io/anon/pen/NqyvWy is identical to the first example in https://material.angularjs.org/HEAD/#/demo/material.components.tabs
except that I added md-stretch-tabs="always" to the md-tabs.
It is not stretched to fit the width of its container.
