gamepad() overrides commands from different controllers

[peagha]

Hello! 👋

When I bind the same button in different controllers it seems the last bind wins; I expected to be able to have one binding per controller+button+modifier, but they appear to be only scoped to button+modifier:

Example 1: two Xbox Wireless Controllers (different device IDs), same button+modifier:

mode: command
-
# Xbox Wireless Controller (device 1) — 0300.5e04.130b.1705
gamepad(0300.5e04.130b.1705:south:down): user.gamepad_pressed("right")
gamepad(0300.5e04.130b.1705:south:up):   user.gamepad_released("right")

# Xbox Wireless Controller (device 2) — 0300.5e04.210b.2305
gamepad(0300.5e04.210b.2305:south:down): user.gamepad_pressed("right")
gamepad(0300.5e04.210b.2305:south:up):   user.gamepad_released("right")

Expected: both controllers trigger their respective bindings independently.
Actual: adding the second binding breaks the first, only the last-defined south:down fires, regardless of which physical controller sent the event.

Note: this does not reproduce when the modifiers differ -> e.g. south:down and south (no modifier) coexist fine.

Talon: 0.4.0-1050-3c4a (1050), macos sequoia and macos tahoe
I have observed this conflict for a long time. So, not something related to a new update. I have never managed to make this work.
