角材料md-select可以将背景切到内容边缘吗？

Question

I updated to angular-material 0.9 and now when I open md-select it cuts off the background to the edge of the content. Is there some way to avoid this?

<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>
