Please describe your issue in as much detail as possible:

While the Steam Deck is docked, turning on the Steam Controller in dongle receiver mode should wake the Steam Deck and operate with the controller normally. Instead, all inputs from the controller happen twice until an input is received from the handheld's gamepad controls, at which point the controller inputs are normal.

Steps for reproducing this issue:

1. Attach the Steam Deck to a Steam Dock with a paired Steam Controller receiver plugged into USB.
2. Wake Steam Deck by turning on Steam Controller in receiver mode.
3. Apply inputs with Steam Controller.
