Scatter3D does not remember its visual state in certain conditions

[kirsan31]

Visual state is zoom level, orientation, position, etc...
Checking for saving state: simply click on one of this control buttons: or call Plotly.restyle. None of these actions should change the visual state.

Bugs briefly:

1. Mouse wheel zooming not saving last zoom lvl (always reverted to previous zoom lvl).
2. Touch pad zooming/rotating/moving not saved at all.

---

Сonditions under which the visual state is not preserved:

Zoom without mouse click - by mouse wheel.
Each odd iteration of zoom level with mouse wheel - will not be remembered. Why odd? Because plotly will save previous zoomlvl after next zoom. In other words - mouse wheel zoomlvl will be reverted 1 step back after restyle or other refresh actions.

PL.mp4

This make mouse wheel zooming not usable with updating by time interval (Plotly.restyle) plots. Side note - if your click any where in the plot after mouse wheel zoom - zoomlvl will be stored.

Any plot manipulation with touch pad.
Here same behavior - touch any where in the plot after manipulating - will store visual state. See video below.

Repro: https://codepen.io/k_sze/pen/WXgNoJ (from #2181). You can click buttons or call restyle() function in console.

Thanks for the bug report! I think it might be related to #5050 and/or #5005

@nicolaskruchten yes, it's looks similar. But I need to point out, that mouse wheel zoom bug exists in every Scatter3D plot without additional conditions (like react in your examples) :(

Indeed, something is going wrong with our camera positioning system... No one on the Plotly team has available bandwidth to look into these right now but we'd love some help fixing these issues!
