CocoonJS scale is not working properly

Hello

I have some weird results with scale mode on CocoonJS. No matter what i choose (Scale to fit, Stretch to fill, Scale to fill) game window isn't scale properly and it's align to one side, (on the other side is a gap). I know that some other people have it too. Anybody found a solution to fix it?

See How to export to CocoonJS. Only 'Scale inner' and 'Scale outer' are supported on CocoonJS, and that means having to support multiple aspect ratios as described in supporting multiple screen sizes.
