Javascript events being ignored until the scene is touched.

Description:

• A-Frame Version: 0.8.2
• Platform / Device: Android and iOS touch devices
• Reproducible Code Snippet or URL: http://reslife360.blackswaninteractive.com/main-aframe-0.8.2.html

We are having an issue where two buttons that our outside of the aframe scene are being used to lad a new template in the scene. This works great on a desktop with a mouse, but on a touch device, either iOS or Android the button doesn't load the new scene, it just refreshes the current one. If, however, you tap the scene at all before clicking the button it works as expected.

An easy way to reproduce this is to click the link above > Founders Hall > click on the back button in the bottom left (same scene will refresh)

However click the link above > Founders Hall > tap anywhere on the scene > click on the back button in the bottom left > you'll return back to the previous scene

Start with the linked reproduction at reslife360.blackswaninteractive.com/main-aframe-0.8.2.html and follow the Founders Hall and back-button steps on Android or iOS. Compare the button behavior before and after tapping the A-Frame scene; done means the external buttons load the intended scene without requiring a prior scene tap.
