How can i place hnotes over two participants?

Question

Its possible to place notes over two participants:

 

Bob -> Alice : hello
note over Bob, Alice
   a note
end note

 

The example does not work properly taking hnote or rnote (PlantUML ver. 8009): The note is placed only over the first mentioned participant.

Hello U.,

Just to answer to an old unanswered question (and confirm that is now OK):

@startuml
Bob -> Alice : hello
Alice -> Charlie: hello

note over Bob, Alice
   note over Bob, Alice
end note

hnote over Bob, Alice
   hnote over Bob, Alice
end note

rnote over Bob, Alice
   rnote over Bob, Alice
end note
