4. Place down the given command block minecart
5. Observe that the command and any other settings do not take affect

Extra Information
The 1.19.10 changelogs added "Advanced Pick Block now copies the items inside when used on a Boat with Chest (MCPE-153410)" meaning it is possible to get data from entites
This feature works properly in Java Edition
