Axis labels and tick labels in 3D plots do not use fonts loaded from remote server

I have an HTML export of a 3D figure created using the Python API. For website embedding, I load a custom font from a server. For the example here, I'll just use a Google Font with a distinct style:

<link
  href="http://fonts.googleapis.com/css?family=Audiowide"
  rel="stylesheet"
  type="text/css"
/>

I include a template in the plot layout so that this font is used for axis labels, tick labels, and et cetera. For 2D plots, this works as expected. For 3D plots, the axis and tick labels do not use the font at all.

I can't share the HTML export, but I recreated a minimal example from scratch to demonstrate this using Plotly.js:

plotly-3d-graph-font-issue.html.zip

Inizia eseguendo l’esempio HTML minimo di Plotly.js allegato all’issue e confronta la gestione dei font tra i suoi grafici 2D e 3D. Traccia il percorso di rendering degli assi 3D e delle etichette dei tick; il lavoro è completato quando i font caricati da remoto vengono applicati a quelle etichette come nei grafici 2D.
