Expected behavior When setting data-mdb-filter="true", the secondary text should be included inside filter.

Actual behavior The secondary text is ignored inside filter

Resources (screenshots, code snippets etc.)

<select class="select" data-mdb-option-height="44" data-mdb-filter="true">
  <option value="1" data-mdb-secondary-text="Secondary text">One</option>
  <option value="2" data-mdb-secondary-text="Secondary text">Two</option>
  <option value="3" data-mdb-secondary-text="Secondary text">Three</option>
  <option value="4" data-mdb-secondary-text="Secondary text">Four</option>
  <option value="5" data-mdb-secondary-text="Secondary text">Five</option>
</select>

Is there a way to support filtering for "One", "Two"... inside the secondary-text?

Thanks a lot.
