It renders when you deactivate it. This works:

sequenceDiagram
    A ->>+ B : something
    B ->>- A : something else

Maybe a notice indicating this can be added to the docs?

I faced the same issue. Is it the intended behavior? I need to create a diagram where some actors do not deactivate. I'd expect the bar to be visible and continue all the way to the bottom.

I would also like to see that the actors remain activated until the bottom without the need to deactivate it. A somewhat similar request: #2897
