JOYSTICK_TYPE_MULTI_AXIS detected as mouse at the same time

Description of Issue

While attempting to use an Arduino Micro with the JoystickLibrary on JOYSTICK_TYPE_MULTI_AXIS mode, the computer immediately locks its mouse pointer to the Arduino's signal. Joystick still operates as a joystick in parallel with the mouse actions.

I've tried the other modes (JOYSTICKTYPE(...)) and they don't hijack the mouse pointer.

I plan to use multiple axis to read a flight sim chair (flight controls, throttle, breaks, mixture and prop pitch control) so, not sure if the other modes are capable, apart from having a dead zone, undesirable for my purpose.

Additional context

I've read somewhere that there's an xorg-joystick driver intended to read a joystick as a mouse pointer and, being similar to my issue I've double-checked, and said driver is not installed on my xorg.

Thanks for your help.
