Mermaid class diagram view is broken (Gitlab 12.6.2-ee)
Summary
In an on premise Gitlab 12.6.2-ee installation, mermaid class diagram views are broken. The view looks not like in the Mermaid Live Editor. If you view for example sequence class diagrams (written in mermaid), everything looks fine. We had the same issue in Gitlab 12.5.0-ee and Gitlab 12.5.3-ee. (using docker images from official gitlab/gitlab-ee:12.X.X-ee repository).
Steps to reproduce
- create any class diagram (written in mermaid) in .md file in gitlab, e.g. with
```mermaid
classDiagram
Class01 <|-- AveryLongClass : Cool
Class03 *-- Class04
Class05 o-- Class06
Class07 .. Class08
Class09 --> C2 : Where am i?
Class09 --* C3
Class09 --|> Class07
Class07 : equals()
Class07 : Object[] elementData
Class01 : size()
Class01 : int chimpa
Class01 : int gorilla
Class08 <--> C2: Cool label
Do not forget at the end the missing. ```
.
- View the markdown file via gitlab gui and see the broken class diagram view.
