Testet in v.8026
Packages without content (classes or notes) will not be drawn according to their package style
@startuml
package AAA <<Frame>> {
}
package BBB <<Frame>> {
class Foo{
}
}
package XXX <<Database>> {
}
package YYY <<Database>> {
note "Hello World" as hello
}
@enduml
The same occurs with all other styles too.
