> For simplicity, I'll use only one combination of portrait and landscape to 
> describe the issue.
> 1. Begin with the device locked in Portrait 
> (screen.orientation.lock('portrait') has been invoked). 
> 2. Physically rotate the device to landscape. Observe that the viewport does 
> not rotate (correct function).
> 3. invoke screen.orientation.lock('landscape')
> 4. Observe that the viewport does not rotate to landscape, although the 
> device's orientation remains locked. 
> This can be reproduced by reversing landscape and portrait as well. Observed 
> on iOS 11 with cordova engine 4.4.0, screen-orientation 2.0.1, and statusbar 
> 2.2.3. 
> The attached cordova project will reproduce this issue. It begins by 
> unlocking the orientation. After 5 seconds, it locks the orientation to 
> landscape. When this happens, physically rotate the device to portrait. After 
> 5 seconds, it will attempt to lock itself to portrait, but fail to do so. 
> The current workaround seems to be to re-invoke a lock to the device's 
> currently locked orientation prior to locking to the new orientation - see 
> the "fixed" project for an example of that.
