Palcing 2 or more any kind of minecarts that make look like a roller coaster train and nodge them even there's a block next to the outermost any kind of minecart and activating it using a powered rail will stuck each other

I activate a 3 minecart using a powered rail. It doesn't work and I test it. It doesn't work all kinds of minecarts. even nodge them. making impossible to use a roller coaster train. Thus, only single minecart will work. Unknown if is expanded into beta 1.13.0.2 due to a MCPE-48069
