Hello, I tested your branch against mediawiki 1.35 ; and ... with 10.2.1 (also with others 10.x) firefox chokes on "SyntaxError: function statement requires a name" ; couldn't spot the exact problem on minified javascript, but the 10.x.x versions all seems to have the same symptoms. (and btw Chrome also shows the same error).

When editing your package.json to go back to mermaid 9.4.3 it runs fine.

Is there a requirement somewhere on yarn version (1.22.5) or other system tool maybe ?

@antibarbie the problem you're getting is probably from how the mediawiki resourceloader minifies everything, including already-minified vendored packages like this one. There is an install script that adds a /*@nomin*/ tag to the top of the file when you install it via composer, but that wouldn't get triggered if you just cloned it from git. added it manually in https://github.com/SemanticMediaWiki/Mermaid/pull/102 , which works from a clone.

TBH right now I don't understand, if I could or should do anything else. Is there something needed from my side?

Ah, already surpassed: https://github.com/SemanticMediaWiki/Mermaid/pull/102 Closing this one.
