There are some problems with the widget rendering on the compwa.github.io/polarimetry website that used to work on the lc2pkpi-polarimetry.docs.cern.ch. This is due to dependency updates since that website was published (and frozen).

• Plotly plots do not render, see for instance https://compwa.github.io/polarimetry/uncertainties.html
• That also breaks the rendering of MathJax formulas
• The widget page shows a duplicate figure. This can be fixed by closing the figure once it has been exported, when rendering the pages for a static build.
• Not all widget buttons function correctly anymore because AmpForm-DPD uses LaTeX particle names rather than database names for the helicity couplings.
