Can't open context menu on touch screen
I've recently begun using Opera on a Windows tablet and found that right-clicking (by long-pressing, as it's usually done) is extremely unreliable in Opera only. Only very seldom will the context menu actually open, most of the time it will count as a normal click despite waiting for the square that indicates that a right-click will be performed in all other applications.
I am using version 39.0.2256.15 on Windows 10 build 10586.420.
