Bug in displaying the text defined in hovertemplate for Surface

A hovertemplate for Surface defined from customdata consisting in an array of shape (m, n, 3), and defined as follows:

hover = 'theta: %{customdata[0]:.3f}'+\
        '<br>phi: %{customdata[1]: .3f}'+\
        '<br>power: %{customdata[2]:.3f}<extra></extra>'

is displayed correctly only for the default position of the camera.eye. If you rotate the sphere the text is displayed verbatim like in the definition of hovertemplate:

The Python code is posted on forum: https://community.plotly.com/t/surface3d-with-customdata/42708/3.

首先复现链接论坛帖子或图表中的 Surface 示例，然后旋转相机以确认 hovertemplate 替换何时失败。跟踪 Surface 悬停标签的渲染路径；完成的标准是旋转相机后 theta、phi 和 power 值仍保持格式化并完成替换。
