classdiagram not works in mermaid live_editor

[houyf]

I sorry if the question is stupid but it does make me confused.

========== Problem Description ==========

I copyed your demo about the classdiagram to the mermaid live editor, but it happen to failed with promotion " Invalid syntax".

I also found that the live editor docs lack the usage introduction about classdiagram.

Does the live editor not support classdiagram ? Is there any other way to make the code work ?

What should We do please document.

But it is still an experimental feature and there are known bugs.
