Input Group w/ Textarea

Created by: travpeck

The button does not align with the text-area anymore (in both Firefox and IE11).

This worked perfectly fine in Bootstrap 4 Beta:

<div class="input-group">
  <span class="input-group-addon">Id</span>
  <textarea class="form-control" maxlength="1000">Text</textarea>
  <span class="input-group-btn">
    <button class="btn btn-danger" type="button">Delete</button>
  </span>
</div>
