Not every mouse reports back/forward the same way. One that carries them on the HID button page (BTN_SIDE/BTN_EXTRA) gets BUTTON_BACK/BUTTON_FORWARD in the motion button state, which is the only shape the forwarder listened for. A mouse that carries them on the consumer page (AC Back / AC Forward — the common Bluetooth shape, and what Android TV boxes tend to see) produces only synthesized KEYCODE_BACK/KEYCODE_FORWARD, and those were swallowed outright to stop them doubling as Android navigation. On that hardware both side buttons were simply dead. Route the key shape into the same wire buttons, deciding by the DEVICE (it has to be able to be a mouse) rather than by the event's source, since the consumer-page collection is a separate sub-device that may be stamped SOURCE_KEYBOARD. A D-pad-capable device is excluded so an air-mouse remote's BACK stays the couch user's way out of the stream. Both paths now funnel through one press/release helper whose held-set guard collapses a device that reports BOTH into a single wire press.
