title: AppCompat 23.3 Support Vectors no longer work?
body: <p>I was using the support vector drawables added in <a href="http://android-developers.blogspot.com/2016/02/android-support-library-232.html">Support Library 23.2</a> along with AppCompat. I was using vector drawables both with <code>app:srcCompat</code> and inside a <code>StateListDrawable</code> so I could use them with <code>android:drawableLeft</code> for my TextView.</p>
  
  <p>Since upgrading to the 23.3.0 version of AppCompat, only the vectors in <code>app:srcCompat</code> are working. Whenever I reference it the other way I get</p>
  
  <pre><code>FATAL EXCEPTION: main
   java.lang.RuntimeException: Unable to start activity ComponentInfo{com.my.package.name/.MainActivity}: android.view.InflateException: Binary XML file line #8: Error inflating class Button

  </code></pre>
  
  <p>What changed that now causes my support vector drawables to fail in some cases?</p>
