Mobileweb does not respect matrix properties (MatrixCreationDict) set in the constructor of Ti.UI.create2DMatrix(), despite the documentation at docs.appcelerator.com indicating that it should. It works on Android and iOS.
Mobileweb, like Android and iOS, should appropriately apply a MatrixCreationDict passed into the Ti.UI.create2DMatrix() function.
The label will be tilted 45 degrees on Android and iOS. It will not be on Mobileweb.
