Is it possible to silence this so I can still use the images as is?
At the moment, it's not possible to silence this behavior. However, we might consider adding an option for it in the future.
In the meantime, would you be open to migrating to the new syntax?
@startuml
start
:output; <<output>>
:continuous; <<continuous>>
@enduml
The legacy syntax will eventually be deprecated.
Also, do you have a large number of diagrams? That context could help us better understand the impact
