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,
