ExpansionHubMotor.setReversed() stopped working

At some point calling setReversed() on any of our motors stopped taking effect. It worked at some point to flip our motors, but now it doesn't take affect for any motor.

The motor still can run, we can get encoder position / velocity, we can reset the encoder, but setReversed does nothing.

class ShooterSubsystem(Subsystem):
    def __init__(self):
        self.shooter_motor = wpilib.ExpansionHubMotor(0, 0)
        self.shooter_motor.setReversed(True) # Swapping this to False has no effect

Hybrid setup with 2 expansion hubs

Power cycles don't help, and I ssh'd into the systemcore to validate the file is getting deployed correctly

Start with the ShooterSubsystem example in the linked FTC2025Flossie repository and trace the ExpansionHubMotor.setReversed() call. Reproduce the issue on the hybrid setup with two expansion hubs, checking whether motor direction changes while encoder operations still work; done means setReversed(True) and setReversed(False) produce opposite motor directions.
