I have a requirement where right click in an existing website needs be supported in iPad. By convention, right click is converted to long press event in touch enabled devices. I have tested in Chrome in Android devices and it worked while it's broken in Safari in iPad (iPad Air 2, 10.3). Just for reference, I was using this demo site:

Could this be a bug in Safari in iOS devices?
