HTML5 axis shows NAN or Infinity with GamepadExample in Chrome

[helpme2k2]

Description of Issue

When I use the GamepadExample that comes with the library on my Lenoardo and test it against Firefox and Chrome (https://html5gamepad.com/), the two browsers produce different result. Firefox's axis reading are all correct but the axis reading from Chrome v81.0.4044.138 returns NaN (when it should be 0) and +/- infinity (when it should be +/-1).

I figured the above issue only appear if I use the constructor with customized number of axis and button like below,

Joystick_ Joystick(JOYSTICK_DEFAULT_REPORT_ID,JOYSTICK_TYPE_GAMEPAD,
  1, 0,                  // Button Count, Hat Switch Count
  true, true, false,     // X and Y, but no Z Axis
  false, false, false,   // No Rx, Ry, or Rz
  false, false,          // No rudder or throttle
  false, false, false);  // No accelerator, brake, or steering

If I use
Joystick_ Joystick; or even Joystick_ Joystick(JOYSTICK_DEFAULT_REPORT_ID,JOYSTICK_TYPE_GAMEPAD); Although there will be non-used axis and button, but the issue of NaN on Chrome is gone.

I don't know if you should be worried about the html5gamepad test; I have made a set of sim pedals that shows up in chrome with +/- infinity and does not show up at all in mozilla. Despite this, they work perfectly fine in Assetto Corsa.

A piece of software that correctly displays all inputs is one made by Leo Bodnar, called DiView.

You should see the actual information sent by the microcontroller there.

Hope this helps
