tikz ``path'' command

The tikz ``path'' command does not work correctly:

The tikz ``path'' command does not work correctly:

\esempiodisa

In compilation it produces the following message:

In some cases, the default driver fails. You can try the tikz+ option in such cases. It seems to work in your case, but note that it can fail in other cases:

  make4ht pathpattern.tex -f html5-common_domfilters -c ml_make4ht -l -u -s -d ./html/mathjax "mathjax,tikz+"

In my case it works, but it is not reassuring: "... but note that it can fail in other cases."

thank you very much!
