I would've thought the hopper minecart should only accept items when not over powered activator rail, similar to a regular hopper only receiving items when not receiving power? If that isn't how the hopper minecart is intended to operate then it's irritatingly inconsistent with the only other hopper in the game! However this is definitely a bug - experimented with it and found the following:
1. hopper minecart collects items on normal track when initially placed and pushed around by player 2. if the hopper minecart is moved with powered rail it stops picking up items until something changes 3. powered activator rail allows hopper to collect items from ground while activator rail is powered and minecart is still on the activator rail 4. if the hopper minecart leaves the activator rail while the activator rail is unpowered, the minecart will stop collecting items on normal rail 5. if, however, the hopper minecart leaves the activator rail while the activator rail is powered, the minecart will be able to collect items on normal rail
That's all I've found so far, I hope this is helpful for fixing the many bugs with the hopper minecart.
