Egor Chistyakov, you asked how we stumbled into this when we didn't want to do this rotation. I'm working in an 18' wide artboard. I screen grab to reference colors. I place the screen grab, select it, hold the shift key while enlarging it, and then hit the spacebar to move within the artboard, and I get the unwanted rotation. I don't have any use for this tool, so I too would like the option to turn it off. (I'd also like UNDO to work, but it doesn't look like that's the case. I had to go searching online for what keystrokes DO this, to figure out how to undo it.)
