input with data-hint attribute

[vinagrito]

<div class="form-group">
  <input class="form-control floating-label" id="focusedInput" type="text" placeholder="YEARS" data-hint="YOYOYO" />
</div>

results in

Forked the repository checked the test app...all good there
What am I missing?. Am I not including something?
