Warning and Deprecation Warnings?

[rsparrow]

When my html looks like this:

<div>

  <div class="carousel-container" >
    <k2-Carousel id="carousel"></k2-Carousel> 
  </div>

  <div class="menu-container" height="100%" >
    <k2-menu id="menu"></k2-menu>  
  </div>

</div>

And my SCSS like this:

.menu-container {
    @include slideInRight('default');
}


.carousel-container {
    @include fadeIn(); 
}

Animations work but I get these warnings:

DEPRECATION WARNING: The return value of index() will change from "false" to
"null" in future versions of Sass. For compatibility, avoid using "== false" on
the return value. For example, instead of "@if index(...) == false", just write
"@if not index(...)".

Is this expected?
