title: TabIndicator disappears when trying to use app:tabIndicator
body: <p>I am trying to assign a custom Drawable to my Tablayout. The Problem is that when I do this, the Tablayout becomes invisible on my Samsung Galaxy S7. No problem at Nexus 5X.</p>
  <h2>Tablayout</h2>
  <pre><code>&lt;com.google.android.material.tabs.TabLayout
