dotted lines between notes and classes

Question

I would like the lines between notes and classes to be dotted.  This is what standard UML diagrams have.

PlantUML actually does render dotted lines when a note is attached to two or more classes.  I'd like the option to have this rendering when a note is attached to one class.

You may use this hack:

@startuml
class a
note "note" as b

a . b
a .[hidden] b
