Compare orientation bug on Windows Phone 8

Touch object's Compare orientation doesn't work on Windows Phone 8. (I've only tested in the native browser (IE?) on Nokia Lumia 1020 Windows Phone 8.0.10328.78)

Here's a test.

Link to .capx file (required!):

gamma.capx

Steps to reproduce:

1. Add touch object

2. Add text field

3. Set text to Touch.compareOrientation

Observed result:

No changes

Expected result:

Changes

Browsers affected:

Chrome: no

Firefox: no

Internet Explorer: yes (the IE-version that's the native browser of Win Phone 8)

Operating system & service pack:

Construct 2 version:

Beta r151.2

Construct 2 retrieves the gamma value in a standards-compliant way, so it simply appears Windows Phone 8 does not support the standard. I'm not sure what we can do about this, but I think the Windows Phone 8.1 update will support it. You could also try publishing to WP8 using PhoneGap, which I think implements a workaround to enable inclinometer input.
