When launching for HTML 5 and using a texture or image that is not a power of two in size the texture does not pan correctly, instead of panning as expected, the material clamps and will remain that way, this issue does not occur if the material/texture is a power of two size.
This issue occurs in 4.13.2, 4.14.3, and 4.15.1 binary builds
Result: The image will start to pan across the surface of the cube and then stop
Expected Result: The image should pan with no clamping issues and never visibly stop
