Minor rendering issue on Activity diagram with nested splits and swimlanes

[rbakhshi]

This is minor rendering issue. In the diagram below, notice the aggregate at the end of nested split, it has moved into the "employee" swimlane.

This is beta 19

Code

@startuml

|Manager|
start
:start here;

split
    :do this;

    split
        :maybe this;
    split again
        :well what about this one?;
    end split

split again
    :or this one;
split again
    |Employee|
    :some other;
end split
|Manager|
stop
