mdSlider: creating a md-content scrollbar when md-sidenav is closed by default

[peluprvi]

The error occurs when you have a md-content, with a md-slider inside, and a md-sidenav which is closed by default and became .md-is-locked-open after a few time.

<div layout="row" flex>
    <md-sidenav layout="column" class="md-sidenav-left md-whiteframe-z2" md-component-id="left" md-is-locked-open="$mdMedia('gt-sm') && isLoggedIn">

    </md-sidenav>
    <div layout="column" flex id="content">
        <md-content layout="column" flex class="md-padding">
          <div layout>
            <div flex="10" layout layout-align="center center">
              <span>default</span>
            </div>
            <md-slider flex md-discrete ng-model="rating1" step="1" min="1" max="5" aria-label="rating">
            </md-slider>
          </div>
        </md-content>
    </div>
