Other browsers tested: FireFox, Edge
  Add OK or FAIL, along with the version, after other browsers where you
have tested this issue:
     Safari: FAIL
    Firefox: OK
         IE: FAIL

What steps will reproduce the problem?
(1) Connect more than 4 Gamepads (that aren't already limited by XInput) to a PC
(2) Call navigator.getGamepads()

What is the expected result?

An arbitrary number of Gamepads should be allowed to connect to a PC.

What happens instead?

Chrome's returned GamepadList only supports 4 values.

Please provide any additional information below. Attach a screenshot if
possible.

These sorts of arbitrary limits are hours of developer frustration so hopefully can be avoided while the Gamepad spec is being finalized.
