Steps to reproduce the problem:
1. Set 'orientation: any' on your pwa's manifest (we're using 'display: standalone')
2. Lock your device's orientation
3. Play with your device's orientation, while on your PWA

What is the expected behavior?
The PWA should respect the device's orientation lock.

What went wrong?
It keeps changing the PWA orientation (landscape / portrait) even if the the orientation is locked by the device's configuration.

Did this work before? N/A 

Chrome version: 55.0.2883.91  Channel: stable
OS Version: 6.0.1
Flash Version: 

We think this is an importante issue because, as you know, the current PWA users do not benefit from a recently updated manifest. Just on new installations.

ps: waiting for the apk version ;)
