Dual notes on activity diagram doesn't display correctly

Question

Hello,

When I insert 2 notes (one left, one right) on the same activity label the "note arrow" doesn't display anymore.

If I insert only one of the two notes, it appears again, I think it is a bug ?

@startuml
start
-> Test 1;
:Test 2;
note right: No arrow displayed
note left: No arrow displayed
-> Test 4;
:**Test 5;
note right: Arrow displayed
-> Test 6;
:**Test 7;
note left: Arrow displayed
stop
@enduml

Thanks a lot

- When having multiple notes on one side the arrow disappears as well.
- When having e.g. 5 notes on one side with one activity label the spacing between the notes is different between the different notes.
