描述
This may well be related to #5698, but that is a few years old and I'm not entirely sure this is the same behaviour, partly because that issue reports two things.
The mousewheel based zoom fires the plotly_relayout event, but after some interactions the event data is empty. When not empty it seems to lag behind what is being displayed.
Tested using the script below. After rotation with a click drag, the zoom with the mouse wheel scroll hits the "No scene data found" found the first time through, suggesting that the scene has not changed despite it changing visually on screen. The subsequent mouse wheel scrolls report the scene data. A single click, being careful not to drag, then reports a different value, suggesting the data provided by relayout on the mouse wheel scroll zoom is lagging behind the new scene position.

调研方向
首先复现所提供的 HTML 示例，并跟踪 3D 鼠标滚轮缩放期间的 plotly_relayout 事件，尤其是在旋转和点击交互之后。将发出的 scene.camera 数据与屏幕上显示的相机位置进行比较。完成的标准是：每次缩放交互后，事件都能持续报告更新后的相机数据，而不是空值或滞后的值。
