There are additional steps to reproduce this in bug 1300157 and I can reproduce it using these steps:

Steps to reproduce:

1. Hold device in portrait-primary orientation.
2. Listen for the screen.orientation change event.
3. Trigger requestFullScreen.
4. Trigger screen.orientation.lock('landscape-primary')
5. Read the screen.orientation.angle value.

Actual results:

The screen.orientation.angle value is 0. This would make sense if the orientation was still portrait-primary, but not for landscape-primary on this device.


Expected results:

The screen.orientation.angle value should be 90 for this device, as the orientation has changed to landscape-primary.

Note: On Chrome it works fine.

So I'm changing the bug to New.
