Activity -Diagram with Swimlanes and splits/if - generates diagram with a lot of whitespace

Question

Hello,

when creating an activity diagram spanning over multiple swimlanes and when using "if" or "split", then PlantUML generates a lot of whitespace (by not putting items below each other but it seems it's placing items into distinct "columns" - see "Actor A" and "Actor B" in the example below).

Is there a way to prevent this?

Thank you, Andreas

        if (Some condition shown here) then (no)
                :Some random action;
                
                :Some random action;
                end;
        else
                :Some random action;
                detach;
        endif;

        else (otherwise)
                :Some random action;
                end;
        endif

end split
