I've tried to test this as precisely as possible and there is definitely an issue here:
1. Perform a "Previous" gesture (RightCLick + MouseMoveUp)
2. Keep doing this, and tell me if you don't end up with a New Tab sooner or later.
The New Tab gesture is (RightClick + MouseMoveDown then MouseMoveUp), but I was careful to make no downward movement once the mousebutton had been clicked.
The 3rd or 4th Previous gesture is usually being turned into a "New Tab"
Does anyone else find this?
THanks
