title: CollapsingToolbarLayout and TabLayout results in title overlapping
body: <p>I'm using the CollapsingToolbarLayout and I'm trying to make the title of the activity fall nicely into its Toolbar while not overlapping with the TabLayout.</p>
  
  <p>I've been searching for a couple of hours and most of the answers suggested a custom height for the Toolbar, but this results in the Title going into the lower part of the toolbar (android:gravity="bottom"). Tried changing its gravity with no luck.</p>
  
  <p>Is there any way of doing this?</p>
  
  <p>This is what I am getting right now:

  <p>My XML layout is as following:</p>
