Fist, for the record...
Confirmed.

I can also confirm that TEC's feature branch does not have this bug.

On main, the bug is caused by horrible heuristics in
`org-html--latex-environment-numbered-p' and
`org-html--unlabel-latex-environment', which make a naive assumption
that \begin{foo*} is always available and codifies unnumbered version of
environment.

However, \begin{tikzpicture*} environment is not valid. Moreover,
\begin{tikzpicture} is not numbered either (just as many other
non-equation environments).

That said, I am not sure what is going on with numbering in TEC's branch
- the above two functions are left in the code, __unused__. Which
indicates that we might also have some feature regression on that branch.
Timothy, any comments?
