Navbar w/o navbar-brand breaks with navbar-toggler-right(-left)

Created by: iatek

When you create a navbar with only a navbar-nav component (no navbar-brand), and then use navbar-toggler-right or navbar-toggler-left, the entire navbar height collapses when the toggler is shown.

A workaround I've found is to use an navbar-text placeholder...

<nav class="navbar navbar-toggleable-md navbar-light bg-faded">
  <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarToggler1" aria-controls="navbarToggler1" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon">&nbsp;</span>
  </button>
  <span class="navbar-text">&nbsp;</span>
  <div class="collapse navbar-collapse" id="navbarToggler1">
    <ul class="navbar-nav mr-auto mt-2 mt-md-0">
      <li class="nav-item active">
        <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">Link</a>
      </li>
      <li class="nav-item">
        <a class="nav-link disabled" href="#">Disabled</a>
      </li>
    </ul>
    <form class="form-inline my-2 my-lg-0">
      <input class="form-control mr-sm-2" type="text" placeholder="Search">
      <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
    </form>
  </div>
</nav>
