ion-content not correctly sized when hardware keyboard active on Android

[moldstadt]

I'm submitting a ... (check one with "x") [x] bug report [ ] feature request

Current behavior:

If I create a page with a transparent ion-footer with multiple lines of content and a background image for the page, and then open keyboard on Android, the content is partially visible behind the footer.

Expected behavior:

The content should remain hidden behind the footer, like it is when the keyboard is not active.

Steps to reproduce:

Start a new ionic blank project and change the home page as below. Build and run on Android emulator. Notice that the content text is behind the footer. Select the input box to show the keyboard, and notice that the text is now visible behind the footer.

    </ion-title>
  </ion-navbar>
</ion-header>
