  <p>I've tried wrapping v-toolbar-title in h6. then adding h6 the #title section as well, but the title is still not changing size. I've also tried using px, %, and rem for the font size.</p>
  <p>I assume that there is probably a size limit inside of an app-toolbar, but no matter which size I choose, it's still not changing.</p>
