我更新为angular-material 0.9，现在当我打开md-select时，它会切断背景到内容的边缘。有没有办法避免这种情况？

<div class="background">
<div layout="column" layout-align="center center" flex>
  <md-select placeholder="Pick">
    <md-option value="1">One</md-option>
    <md-option value="2">Two</md-option>
  </md-select>
    </div>
  <p>The background ends at the content when md-select is open</p>
</div>
