Pop-over opactity 0?

Going through creating samples I couldn’t see my ion-popover-view. I notice in the css that the popover class has opactity: 0. I can only see my popover if I add opactity: 100 to my ion-popover-view. Am I missing something?

<script id="my-popover.html" type="text/ng-template">
  <ion-popover-view style="opacity: 100">
      <h1 class="title">My Popover Title</h1>

Could you create a demo of this? Everything seems to be working fine in on our codepen demo.

Maybe some conflicted css?

how can i make the popover to view upward not dropdown, i need drop upward, hope there is a way i can do this
