Summary:
when safari is in standalone mode (ie after being added to the homescreen), it automatically display the prompt "The operation could not be completed" if a video is base64 encoded and has the autoplay attribute.

Steps to Reproduce:
1. go to http://codepen.io/patrickkettner/full/DtxJC
2. add the video to the homepage
3. open that link

Expected Results:
1. Nothing. It should not do anything, since the user didn't interact with the video.

Actual Results:
1. The user gets a distracting prompt

Version:
Any ios 7 device (not on the emulator). Specifically testing at the moment on 7.0.4 (11B554a), on model ME348LL/A
