Orthographic projection prevents scene camera updates

(Plotting offline)

Setting the projection to orthographic seems to prevent scene_camera settings being applied. This creates difficulty in saving as non-png images that aren't the default view.

from random import random
from plotly import __version__
import plotly.graph_objects as go

print('version: ', __version__)

version: 4.7.1

x = [random() for each in range(100)]
y = [random()*0.3 for each in range(100)]
z = [random()*0.05 for each in range(100)]

fig = go.Figure()
fig.add_trace(go.Scatter3d(x=x, y=y, z=z))
fig.layout.scene.camera.projection.type = "orthographic"
fig.show()

fig.update_layout(scene_camera=dict(eye=dict(x=5, y=5, z=5)))
fig.show()

fig.update_layout(scene_camera=dict(up=dict(x=0, y=0, z=-1)))
fig.show()

fig.update_layout(scene_camera=dict(center=dict(x=1, y=1, z=1)))
fig.show()

Also, the default view has the plot at a zoom level that crops part of the plot from view for long-shaped plots.

fig.update_layout(scene=dict(aspectmode='data'))
fig.show()

Scroll-zooming still works when plotted interactively.

首先使用 Plotly 4.7.1 运行提供的 Python 复现代码，并比较每次更新 scene_camera 后正交相机的行为。跟踪 3D 场景的离线图像导出路径，然后添加一个涵盖投影类型和相机设置的回归测试。当正交导出应用 eye、up 和 center 设置并保留预期视图时，即表示完成。
