Binding strafe key to something other than default causes strafe to not work when aiming

Platform: PC Steam

Steps To Reproduce: Change strafe left key from default to Q, use right mouse button to aim down sight or scope or binoculars, try to strafe left with Q. Strafe does not work. Putting strafe left on some keys does work, but not Q or a few others. Did not test all keys. Putting strafe right on W key still allows strafe right during aiming with right mouse button.
