On the PlantUML website component diagram example with interfaces results in the diagram being cut off:
http://plantuml.com/component-diagram - Basic example.
Also when I try this on planttext.com
```
@startuml
package "Training Session" {
[Pretraining]
[Training]
[Posttraining]
}
interface "FB1 Train" as FB1Snapshot
interface "FB1 Merge" as FB1Train
FB1Snapshot - [Pretraining]
FB1Train - [Posttraining]
[Pretraining] --> [Training]
[Training] --> [Posttraining]
@enduml
```
It also shows that the interfaces get cut off in the resulting diagram.
