I just tried that out. As I mentioned here:https://lists.gnu.org/archive/html/emacs-orgmode/2023-08/msg00092.html, I found that, when using the dvisvgm option for exporting TeX snippets to HTML, the displayed math enclosed by \[…\] is not rendered as equation block, while math environments enclosed by \begin{…} \end{…} are rendered correctly.

Also, the org-latex-preview also rendered (deliberately put) inline \[…\] as inline images.

I guess it could be caused by org-latex-math-environments-re. Could you add support to recognize \[…\] also as equations? Thank you.
