Bug report

Problem
STRIG(x) returns the wrong buttons.

With Xbox 360 controller plugged into Windows 10 machine, and I run this program:

10 SCREEN 0:WIDTH 80
20 FOR I=0 TO 3:XY(I)=STICK(I):NEXT I
30 FOR I=0 TO 7:B(I)=STRIG(I):NEXT I
40 PRINT "Joy1:";XY(0);XY(1);B(0);B(1);B(4);B(5);"Joy2:";XY(2);XY(3);B(2);B(3);B(6);B(7)
50 GOTO 20

I see this option when pressing A and B buttons on joystick 1:

Joy1: 130  136 -1 -1  0  0 Joy2: 0  0  0 -1  0  0                               
Joy1: 130  136  0 -1  0  0 Joy2: 0  0  0 -1  0  0                               
Joy1: 130  136  0 -1  0  0 Joy2: 0  0  0 -1  0  0                               
Joy1: 130  136  0 -1  0  0 Joy2: 0  0  0  0  0  0                               
Joy1: 130  136  0 -1  0  0 Joy2: 0  0  0  0  0  0           

This corresponds to STRIG(x) for x = 0,1,2,3.
But the documentation:
https://robhagemans.github.io/pcbasic/doc/1.2/#STRIG-function
Says that x = 0,1,4,5 are joystick 1.
2,3,6,7 are joystick 2.

Is the documentation wrong?
Or is PC BASIC emulation wrong?
Perhaps PC-BASIC could allow remapping of controller buttons, in case this is not clear, or in case Xbox controller does not follow standard button mappings for Windows (I seem to doubt that; it is probably standard).

Steps
See program above.
Run it.
Press A and B on joystick one, and watch the output.
Better yet: plug in joystick two, and see if that works as well (I have not tried).

Program
See above.

Crash log
None.

Notes
