Chrome for Android does not implement completely background-position. Therefore, color picker is rendered bad as can be seen in the attached image. Maybe the problem is not background-position, but I have deduced it because debugging Android web view in Chrome for desktop the color picker is shown correctly in the desktop and bad in the mobile.
I only have tried JavaScript implementation, but I suppose that the issue also happens in jQuery implementation.
Thanks.
