StateDiagram has same problem

[razterizer]

Yep. I got the same problem when the Mermaid Chart plugin in VSCode was updated this morning.

Meanwhile, I'll just add a helper node A --> |action| AH --> A as a cheapo hack to make self-referral "work again".

We can reproduce this and are working on a fix for it in the upcoming release.

@knsv huge thanks for the fix!

i just wanna let you know that now the arrows towards the same node are much wider (i don't know if it was intentional).

graph LR;
    A((A))--test -->A((A))

    B((B))-- another test-->B((B))

    C((C))-- text-->C((C))
    C((C))-- another text-->D((D))

Hi there @knsv, thanks for the fix as well! Now diagrams with self-references render, but I encounter similar issues as @FeddyLix17: the arrows for self-references are way off:
