I've run with the mermaidhtml output a bit as well.  The output looks nice but there are many asan errors, mostly from lost string alloctions - see below.

I had a look at fixing these, but the object lifetime model appears more complex than I could straightforwardly divine - it's not obvious when any given object can be freed.  I suggest that you with your greater understanding would be better placed to fix these.

Thanks,
