Adding in a 3rd portout to an existing component causes the diagram to not render, removing it does render.
This only happens if I have a link with a label, if the link is unrelated to the component/portout
This happens in the old and new online editor, as well as a docker container I am running.
I tried to also increase the plantuml limit size in docker with no success.
UML source
@startuml
package "A" {
component "B" {
portout p1
portout p2
' Commenting out p3 will get this to render
portout p3
}
}
'unrelated link, must be with label
C -> p4 : X
' If I uncomment this following link to the 3rd port, the image will render; BUT only if the link includes the label
' C -> p3 : Y
