This is something I don't remember seeing before 1.10.1 but now the rotate shortcut (⌘ and apple magic mouse scroll) continues to rotate when removing finger from the ⌘ key (I've also assigned a shortcut ⌘` to reset rotation) and when moving to the zoom shortcut (⌥ and apple magic mouse scroll) straight after using the rotate shortcut, it zooms as expected but if you continue to scroll while removing finger from the ⌥ key it rotates - I'd show a video to illustrate but I have no way of capturing key combos - tested on two different macs both running mojave
