LaTeX equations cannot be rendered in org-roam-ui

Phenomenon All LaTeX equations are displayed as UTF-8 symbols in the preview panel of org-roam-ui, which cannot be rendered by KaTeX (reference).

Cause The file names for the fonts used by KaTeX in ~/.emacs.d/elpa/org-roam-ui-20221105.1040/out/_next/static/media have been cut short. So the fonts cannot be found when loading the preview page.

Solution Do not install org-roam-ui via Emacs package-install. Use the org-roam-ui cloned from GitHub https://github.com/org-roam/org-roam-ui.git.

Now everything looks correct.
