What needs to be fixed

The Cassiopeia breadcrumbs module position

Why this should be fixed

At the moment, it is below the component area (see index.php lines 151-157):
<div class="grid-child container-component"> <jdoc:include type="modules" name="main-top" style="cardGrey" /> <jdoc:include type="message" /> <jdoc:include type="component" /> <jdoc:include type="modules" name="breadcrumbs" style="none" /> <jdoc:include type="modules" name="main-bottom" style="cardGrey" /> </div>

<div class="grid-child container-component"> <jdoc:include type="modules" name="breadcrumbs" style="none" /> <jdoc:include type="modules" name="main-top" style="cardGrey" /> <jdoc:include type="message" /> <jdoc:include type="component" /> <jdoc:include type="modules" name="main-bottom" style="cardGrey" /> </div>

So it looks like this:

Side Effects expected

None. (The misalignment at the top of the component and sidebar was already there).
