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

首先运行 issue 中附带的最小 Plotly.js HTML 示例，并比较其中 2D 和 3D 绘图的字体处理方式。跟踪 3D 轴和刻度标签的渲染路径；当远程加载的字体能够像在 2D 绘图中一样应用于这些标签时，即表示完成。
