Steam Input: steam_input_get_gamepad_index_for_controller always returns -1

[HolofighterDev]

Description

I have the latest version of the extension and I've got a vanilla version of the example project. In that, I've opened up the input object and in update_handles, I've added one loop:

for (var i = 0; i < array_length(controllers); i++) {
   show_debug_message(steam_input_get_gamepad_index_for_controller(controllers[i]));
}

This prints out a steady stream of -1. It does this for every connected controller. Running the inverse function on an input of -1 produces the first controller handle the system detected, meaning any others are inaccessible. This indicates to me that this function is broken.

Expected Change

I expect that when I run the example project and connect a controller, using this function on a valid controller handle will return a gamepad index that I can use for input functionality, as it suggests in the documentation.
